37 <title>DESCRIPTION</title>
39 The Pazpar2 configuration file, together with any referenced XSLT files,
40 govern Pazpar2's behavior as a client, and control the normalization and
41 extraction of data elements from incoming result records, for the
42 purposes of merging, sorting, facet analysis, and display.
46 The file is specified using the option -f on the Pazpar2 command line.
47 There is not presently a way to reload the configuration file without
48 restarting Pazpar2, although this will most likely be added some time
56 The configuration file is XML-structured. It must be well-formed XML. All
57 elements specific to Pazpar2 should belong to the namespace
58 <literal>http://www.indexdata.com/pazpar2/1.0</literal>
59 (this is assumed in the
60 following examples). The root element is named "<literal>pazpar2</literal>".
61 Under the root element are a number of elements which group categories of
62 information. The categories are described below.
65 <refsect2 id="config-threads">
66 <title>threads</title>
68 This section is optional and is supported for Pazpar2 version 1.3.1 and
69 later . It is identified by element "<literal>threads</literal>" which
70 may include one attribute "<literal>number</literal>" which specifies
71 the number of worker-threads that the Pazpar2 instance is to use.
72 A value of 0 (zero) disables worker-threads (all work is carried out
76 <refsect2 id="config-server">
79 This section governs overall behavior of a server endpoint. It is identified
80 by the element "server" which takes an optional attribute, "id", which
81 identifies this particular Pazpar2 server. Any string value for "id"
86 elements are described below. From Pazpar2 version 1.2 this is
89 <variablelist> <!-- level 1 -->
94 Configures the webservice -- this controls how you can connect
95 to Pazpar2 from your browser or server-side code. The
96 attributes 'host' and 'port' control the binding of the
97 server. The 'host' attribute can be used to bind the server to
98 a secondary IP address of your system, enabling you to run
99 Pazpar2 on port 80 alongside a conventional web server. You
100 can override this setting on the command line using the option -h.
109 If this item is given, Pazpar2 will forward all incoming HTTP
110 requests that do not contain the filename 'search.pz2' to the
111 host and port specified using the 'host' and 'port'
112 attributes. The 'myurl' attribute is required, and should provide
113 the base URL of the server. Generally, the HTTP URL for the host
114 specified in the 'listen' parameter. This functionality is
115 crucial if you wish to use
116 Pazpar2 in conjunction with browser-based code (JS, Flash,
117 applets, etc.) which operates in a security sandbox. Such code
118 can only connect to the same server from which the enclosing
119 HTML page originated. Pazpar2s proxy functionality enables you
120 to host all of the main pages (plus images, CSS, etc) of your
121 application on a conventional webserver, while efficiently
122 processing webservice requests for metasearch status, results,
129 <term>icu_chain</term>
132 Specifies character set normalization for relevancy / sorting /
133 mergekey and facets - for the server. These definitions serves as
134 default for services that don't have these given. For the meaning
135 of these settings refer to the
136 <xref linkend="icuchain"/> element inside service.
142 <term>relevance / sort / mergekey / facet</term>
145 Obsolete. Use element icu_chain instead.
151 <term>settings</term>
154 Specifies target settings for the server.. These settings serves
155 as default for all services which don't have these given.
156 The settings element requires one attribute 'src' which specifies
157 a settings file or a directory . If a directory is given all
158 files with suffix <filename>.xml</filename> is read from this
160 <xref linkend="target_settings"/> for more information.
169 This nested element controls the behavior of Pazpar2 with
170 respect to your data model. In Pazpar2, incoming records are
171 normalized, using XSLT, into an internal representation.
172 The 'service' section controls the further processing and
173 extraction of data from the internal representation, primarily
174 through the 'metadata' sub-element.
177 Pazpar2 version 1.2 and later allows multiple service elements.
178 Multiple services must be given a unique ID by specifying
179 attribute <literal>id</literal>.
180 A single service may be unnamed (service ID omitted). The
181 service ID is referred to in the
182 <link linkend="command-init"><literal>init</literal></link> webservice
183 command's <literal>service</literal> parameter.
186 <variablelist> <!-- Level 2 -->
188 <term>metadata</term>
191 One of these elements is required for every data element in
192 the internal representation of the record (see
193 <xref linkend="data_model"/>. It governs
194 subsequent processing as pertains to sorting, relevance
195 ranking, merging, and display of data elements. It supports
196 the following attributes:
199 <variablelist> <!-- level 3 -->
204 This is the name of the data element. It is matched
205 against the 'type' attribute of the
207 in the normalized record. A warning is produced if
208 metadata elements with an unknown name are
210 normalized record. This name is also used to
212 data elements in the records returned by the
213 webservice API, and to name sort lists and browse
223 The type of data element. This value governs any
224 normalization or special processing that might take
225 place on an element. Possible values are 'generic'
226 (basic string), 'year' (a range is computed if
227 multiple years are found in the record). Note: This
228 list is likely to increase in the future.
237 If this is set to 'yes', then the data element is
238 includes in brief records in the webservice API. Note
239 that this only makes sense for metadata elements that
240 are merged (see below). The default value is 'no'.
249 Specifies that this data element is to be used for
250 sorting. The possible values are 'numeric' (numeric
251 value), 'skiparticle' (string; skip common, leading
252 articles), and 'no' (no sorting). The default value is
262 Specifies that this element is to be used to
264 records against the user's query (when ranking is
265 requested). The value is an integer, used as a
266 multiplier against the basic TF*IDF score. A value of
267 1 is the base, higher values give additional
269 elements of this type. The default is '0', which
270 excludes this element from the rank calculation.
276 <term>termlist</term>
279 Specifies that this element is to be used as a
280 termlist, or browse facet. Values are tabulated from
281 incoming records, and a highscore of values (with
282 their associated frequency) is made available to the
283 client through the webservice API.
285 are 'yes' and 'no' (default).
294 This governs whether, and how elements are extracted
295 from individual records and merged into cluster
296 records. The possible values are: 'unique' (include
297 all unique elements), 'longest' (include only the
298 longest element (strlen), 'range' (calculate a range
299 of values across all matching records), 'all' (include
300 all elements), or 'no' (don't merge; this is the
307 <term>mergekey</term>
310 If set to '<literal>required</literal>', the value of this
311 metadata element is appended to the resulting mergekey if
312 the metadata is present in a record instance.
313 If the metadata element is not present, the a unique mergekey
314 will be generated instead.
317 If set to '<literal>optional</literal>', the value of this
318 metadata element is appended to the resulting mergekey if the
319 the metadata is present in a record instance. If the metadata
320 is not present, it will be empty.
323 If set to '<literal>no</literal>' or the mergekey attribute is
324 omitted, the metadata will not be used in the creation of a
331 <term id="facetrule">facetrule</term>
334 Specifies the ICU rule set to be used for normalizing
335 facets. If facetrule is omitted from metadata, the
336 rule set 'facet' is used.
345 This attribute allows you to make use of static database
346 settings in the processing of records. Three possible values
347 are allowed. 'no' is the default and doesn't do anything.
348 'postproc' copies the value of a setting with the same name
349 into the output of the normalization stylesheet(s). 'parameter'
350 makes the value of a setting with the same name available
351 as a parameter to the normalization stylesheet, so you
352 can further process the value inside of the stylesheet, or use
353 the value to decide how to deal with other data values.
356 The purpose of using settings in this way can either be to
357 control the behavior of normalization stylesheet in a database-
358 dependent way, or to easily make database-dependent values
359 available to display-logic in your user interface, without having
360 to implement complicated interactions between the user interface
361 and your configuration system.
366 </variablelist> <!-- attributes to metadata -->
372 <term id="icuchain" xreflabel="icu_chain">icu_chain</term>
375 Specifies a named ICU rule set. The icu_chain element must include
376 attribute 'id' which specifies the identifier (name) for the ICU
378 Pazpar2 uses the particular rule sets for particular purposes.
379 Rule set 'relevance' is used to normalize
380 terms for relevance ranking. Rule set 'sort' is used to
381 normalize terms for sorting. Rule set 'mergekey' is used to
382 normalize terms for making a mergekey and, finally. Rule set 'facet'
383 is normally used to normalize facet terms, unless
384 <xref linkend="facetrule">facetrule</xref> is given for a
388 The icu_chain element must also include a 'locale'
389 attribute which must be set to one of the locale strings
390 defined in ICU. The child elements listed below can be
391 in any order, except the 'index' element which logically
392 belongs to the end of the list. The stated tokenization,
393 transformation and charmapping instructions are performed
394 in order from top to bottom.
396 <variablelist> <!-- Level 2 -->
401 The attribute 'rule' defines the direction of the
402 per-character casemapping, allowed values are "l"
403 (lower), "u" (upper), "t" (title).
408 <term>transform</term>
411 Normalization and transformation of tokens follows
412 the rules defined in the 'rule' attribute. For
413 possible values we refer to the extensive ICU
414 documentation found at the
415 <ulink url="&url.icu.transform;">ICU
416 transformation</ulink> home page. Set filtering
417 principles are explained at the
418 <ulink url="&url.icu.unicode.set;">ICU set and
419 filtering</ulink> page.
424 <term>tokenize</term>
427 Tokenization is the only rule in the ICU chain
428 which splits one token into multiple tokens. The
429 'rule' attribute may have the following values:
430 "s" (sentence), "l" (line-break), "w" (word), and
431 "c" (character), the later probably not being
432 very useful in a pruning Pazpar2 installation.
438 From Pazpar2 version 1.1 the ICU wrapper from YAZ is used.
439 Refer to the <ulink url="&url.yaz.yaz-icu;">yaz-icu</ulink>
440 utility for more information.
446 <term>relevance</term>
449 Specifies the ICU rule set used for relevance ranking.
450 The child element of 'relevance' must be 'icu_chain' and the
451 'id' attribute of the icu_chain is ignored. This
452 definition is obsolete and should be replaced by the equivalent
455 <icu_chain id="relevance" locale="en">..<icu_chain>
465 Specifies the ICU rule set used for sorting.
466 The child element of 'sort' must be 'icu_chain' and the
467 'id' attribute of the icu_chain is ignored. This
468 definition is obsolete and should be replaced by the equivalent
471 <icu_chain id="sort" locale="en">..<icu_chain>
478 <term>mergekey</term>
481 Specifies ICU tokenization and transformation rules
482 for tokens that are used in Pazpar2's mergekey.
483 The child element of 'mergekey' must be 'icu_chain' and the
484 'id' attribute of the icu_chain is ignored. This
485 definition is obsolete and should be replaced by the equivalent
488 <icu_chain id="mergekey" locale="en">..<icu_chain>
498 Specifies ICU tokenization and transformation rules
499 for tokens that are used in Pazpar2's facets.
500 The child element of 'facet' must be 'icu_chain' and the
501 'id' attribute of the icu_chain is ignored. This
502 definition is obsolete and should be replaced by the equivalent
505 <icu_chain id="facet" locale="en">..<icu_chain>
512 <term>settings</term>
515 Specifies target settings for this service. Refer to
516 <xref linkend="target_settings"/>.
525 Specifies timeout parameters for this service.
526 The <literal>timeout</literal>
527 element supports the following attributes:
528 <literal>session</literal>, <literal>z3950_operation</literal>,
529 <literal>z3950_session</literal> which specifies
530 'session timeout', 'Z39.50 operation timeout',
531 'Z39.50 session timeout' respectively. The Z39.50 operation
532 timeout is the time Pazpar2 will wait for an active Z39.50/SRU
533 operation before it gives up (times out). The Z39.50 session
534 time out is the time Pazpar2 will keep the session alive for
535 an idle session (no operation).
538 The following is recommended but not required:
539 z3950_operation (30) < session (60) < z3950_session (180) .
540 The default values are given in parantheses.

595 regular Shell like glob-pattern. For example,

601 The include facility requires Pazpar2 version 1.2.
605 <refsect1 id="target_settings">
606 <title>TARGET SETTINGS</title>
608 Pazpar2 features a cunning scheme by which you can associate various
609 kinds of attributes, or settings with search targets. This can be done
610 through XML files which are read at startup; each file can associate
611 one or more settings with one or more targets. The file format is generic
612 in nature, designed to support a wide range of application requirements. The
613 settings can be purely technical things, like, how to perform a title
614 search against a given target, or it can associate arbitrary name=value
615 pairs with groups of targets -- for instance, if you would like to
616 place all commercial full-text bases in one group for selection
617 purposes, or you would like to control what targets are accessible
618 to users by default. Per-database settings values can even be used
619 to drive sorting, facet/termlist generation, or end-user interface display
624 During startup, Pazpar2 will recursively read a specified directory
625 (can be identified in the pazpar2.cfg file or on the command line), and
626 process any settings files found therein.
630 Clients of the Pazpar2 webservice interface can selectively override
631 settings for individual targets within the scope of one session. This
632 can be used in conjunction with an external authentication system to
633 determine which resources are to be accessible to which users. Pazpar2
634 itself has no notion of end-users, and so can be used in conjunction
635 with any type of authentication system. Similarly, the authentication
636 tokens submitted to access-controlled search targets can similarly be
637 overridden, to allow use of Pazpar2 in a consortial or multi-library
638 environment, where different end-users may need to be represented to
639 some search targets in different ways. This, again, can be managed
640 using an external database or other lookup mechanism. Setting overrides
641 can be performed either using the
642 <link linkend="command-init">init</link> or the
643 <link linkend="command-settings">settings</link> webservice
648 In fact, every setting that applies to a database (except pz:id, which
649 can only be used for filtering targets to use for a search) can be overridden
650 on a per-session basis. This allows the client to override specific CCL fields
651 for searching, etc., to meet the needs of a session or user.
655 Finally, as an extreme case of this, the webservice client can
656 introduce entirely new targets, on the fly, as part of the
657 <link linkend="command-init">init</link> or
658 <link linkend="command-settings">settings</link> command.
659 This is useful if you desire to manage information
660 about your search targets in a separate application such as a database.
661 You do not need any static settings file whatsoever to run Pazpar2 -- as
662 long as the webservice client is prepared to supply the necessary
663 information at the beginning of every session.
668 The following discussion of practical issues related to session
669 and settings management are cast in terms of a user interface based on
670 Ajax/Javascript technology. It would apply equally well to many other
671 kinds of browser-based logic.
676 Typically, a Javascript client is not allowed to directly alter the
677 parameters of a session. There are two reasons for this. One has to do
678 with access to information; typically, information about a user will
679 be stored in a system on the server side, or it will be accessible in
680 some way from the server. However, since the Javascript client cannot
681 be entirely trusted (some hostile agent might in fact 'pretend' to be
682 a regular ws client), it is more robust to control session settings
683 from scripting that you run as part of your webserver. Typically, this
684 can be handled during the session initialization, as follows:
688 Step 1: The Javascript client loads, and asks the webserver for a
689 new Pazpar2 session ID. This can be done using a Javascript call, for
690 instance. Note that it is possible to submit Ajax HTTPXmlRequest calls
691 either to Pazpar2 or to the webserver that Pazpar2 is proxying
692 for. See (XXX Insert link to Pazpar2 protocol).
696 Step 2: Code on the webserver authenticates the user, by database lookup,
697 LDAP access, NCIP, etc. Determines which resources the user has access to,
698 and any user-specific parameters that are to be applied during this session.
702 Step 3: The webserver initializes a new Pazpar2 settings, and sets
703 user-specific parameters as necessary, using the init webservice
704 command. A new session ID is returned.
708 Step 4: The webserver returns this session ID to the Javascript
709 client, which then uses the session ID to submit searches, show
714 Step 5: When the Javascript client ceases to use the session,
715 Pazpar2 destroys any session-specific information.
719 <title>SETTINGS FILE FORMAT</title>
721 Each file contains a root element named <settings>. It may
722 contain one or more <set> elements. The settings and set
723 elements may contain the following attributes. Attributes in the set
724 node overrides those in the setting root element. Each set node must
725 specify (directly, or inherited from the parent node) at least a
726 target, name, and value.
734 This specifies the search target to which this setting should be
735 applied. Targets are identified by their Z39.50 URL, generally
736 including the host, port, and database name, (e.g.
737 <literal>bagel.indexdata.com:210/marc</literal>).
738 Two wildcard forms are accepted:
739 * (asterisk) matches all known targets;
740 <literal>bagel.indexdata.com:210/*</literal> matches all
741 known databases on the given host.
744 A precedence system determines what happens if there are
745 overlapping values for the same setting name for the same
746 target. A setting for a specific target name overrides a
747 setting which specifies target using a wildcard. This makes it
748 easy to set defaults for all targets, and then override them
749 for specific targets or hosts. If there are
750 multiple overlapping settings with the same name and target
751 value, the 'precedence' attribute determines what happens.
754 For Pazpar2 1.6.4 or later, the target ID may be user-defined, in
755 which case, the actual host, port, etc is given by setting
756 <xref linkend="pzurl"/>.
764 The name of the setting. This can be anything you like.
765 However, Pazpar2 reserves a number of setting names for
766 specific purposes, all starting with 'pz:', and it is a good
767 idea to avoid that prefix if you make up your own setting
768 names. See below for a list of reserved variables.
776 The value of the setting. Generally, this can be anything you
777 want -- however, some of the reserved settings may expect
778 specific kinds of values.
783 <term>precedence</term>
786 This should be an integer. If not provided, the default value
787 is 0. If two (or more) settings have the same content for
788 target and name, the precedence value determines the outcome.
789 If both settings have the same precedence value, they are both
790 applied to the target(s). If one has a higher value, then the
791 value of that setting is applied, and the other one is ignored.
798 By setting defaults for target, name, or value in the root
799 settings node, you can use the settings files in many different
800 ways. For instance, you can use a single file to set defaults for
801 many different settings, like search fields, retrieval syntaxes,
802 etc. You can have one file per server, which groups settings for
803 that server or target. You could also have one file which associates
804 a number of targets with a given setting, for instance, to associate
805 many databases with a given category or class that makes sense
806 within your application.
810 The following examples illustrate uses of the settings system to
811 associate settings with targets to meet different requirements.
815 The example below associates a set of default values that can be
816 used across many targets. Note the wildcard for targets.
817 This associates the given settings with all targets for which no
818 other information is provided.
820 <settings target="*">
822 <!-- This file introduces default settings for pazpar2 -->
824 <!-- mapping for unqualified search -->
825 <set name="pz:cclmap:term" value="u=1016 t=l,r s=al"/>
827 <!-- field-specific mappings -->
828 <set name="pz:cclmap:ti" value="u=4 s=al"/>
829 <set name="pz:cclmap:su" value="u=21 s=al"/>
830 <set name="pz:cclmap:isbn" value="u=7"/>
831 <set name="pz:cclmap:issn" value="u=8"/>
832 <set name="pz:cclmap:date" value="u=30 r=r"/>
834 <set name="pz:limitmap:title" value="rpn:@attr 1=4 @attr 6=3"/>
835 <set name="pz:limitmap:date" value="ccl:date"/>
837 <!-- Retrieval settings -->
839 <set name="pz:requestsyntax" value="marc21"/>
840 <set name="pz:elements" value="F"/>
842 <!-- Query encoding -->
843 <set name="pz:queryencoding" value="iso-8859-1"/>
845 <!-- Result normalization settings -->
847 <set name="pz:nativesyntax" value="iso2709"/>
848 <set name="pz:xslt" value="../etc/marc21.xsl"/>
856 The next example shows certain settings overridden for one target,
857 one which returns XML records containing DublinCore elements, and
858 which furthermore requires a username/password.
860 <settings target="funkytarget.com:210/db1">
861 <set name="pz:requestsyntax" value="xml"/>
862 <set name="pz:nativesyntax" value="xml"/>
863 <set name="pz:xslt" value="../etc/dublincore.xsl"/>
865 <set name="pz:authentication" value="myuser/password"/>
871 The following example associates a specific name/value combination
872 with a number of targets. The targets below are access-restricted,
873 and can only be used by users with special credentials.
875 <settings name="pz:allow" value="0">
876 <set target="funkytarget.com:210/*"/>
877 <set target="commercial.com:2100/expensiveDb"/>
885 <title>RESERVED SETTING NAMES</title>
887 The following setting names are reserved by Pazpar2 to control the
888 behavior of the client function.
893 <term>pz:cclmap:xxx</term>
896 This establishes a CCL field definition or other setting, for
897 the purpose of mapping end-user queries. XXX is the field or
898 setting name, and the value of the setting provides parameters
899 (e.g. parameters to send to the server, etc.). Please consult
900 the YAZ manual for a full overview of the many capabilities of
901 the powerful and flexible CCL parser.
904 Note that it is easy to establish a set of default parameters,
905 and then override them individually for a given target.
909 <varlistentry id="requestsyntax">
910 <term>pz:requestsyntax</term>
913 This specifies the record syntax to use when requesting
914 records from a given server. The value can be a symbolic name like
915 marc21 or xml, or it can be a Z39.50-style dot-separated OID.
920 <term>pz:elements</term>
923 The element set name to be used when retrieving records from a
929 <term>pz:piggyback</term>
932 Piggybacking enables the server to retrieve records from the
933 server as part of the search response in Z39.50. Almost all
934 servers support this (or fail it gracefully), but a few
935 servers will produce undesirable results.
936 Set to '1' to enable piggybacking, '0' to disable it. Default
937 is 1 (piggybacking enabled).
942 <term>pz:nativesyntax</term>
945 Specifies how Pazpar2 shoule map retrieved records to XML. Currently
946 supported values are <literal>xml</literal>,
947 <literal>iso2709</literal> and <literal>txml</literal>.
950 The value <literal>iso2709</literal> makes Pazpar2 convert retrieved
951 MARC records to MARCXML. In order to convert to XML, the exact
952 chacater set of the MARC must be known (if not, the resulting
953 XML is probably not well-formed). The character set may be
955 <literal>;charset=</literal><replaceable>charset</replaceable> to
956 <literal>iso2709</literal>. If omitted, a charset of
957 MARC-8 is assumed. This is correct for most MARC21/USMARC records.
960 The value <literal>txml</literal> is like <literal>iso2709</literal>
961 except that records are converted to TurboMARC instead of MARCXML.
964 The value <literal>xml</literal> is used if Pazpar2 retrieves
965 records that are already XML (no conversion takes place).
971 <term>pz:queryencoding</term>
974 The encoding of the search terms that a target accepts. Most
975 targets do not honor UTF-8 in which case this needs to be specified.
976 Each term in a query will be converted if this setting is given.
982 <term>pz:negotiation_charset</term>
985 Sets character set for Z39.50 negotiation. Most targets do not support
986 this, and some will even close connection if set (crash on server
987 side or similar). If set, you probably want to set it to
988 <literal>UTF-8</literal>.
997 Is a comma separated list of of files that specifies
998 how to convert incoming records to the internal representation.
1001 The suffix of each file specifies the kind of tranformation.
1002 Suffix "<literal>.xsl</literal>" makes an XSL transform. Suffix
1003 "<literal>.mmap</literal>" will use the MMAP transform (described below).
1006 The special value "<literal>auto</literal>" will use a file
1007 which is the <link linkend="requestsyntax">pz:requestsyntax's</link>
1009 <literal>'.xsl'</literal>.
1012 When mapping MARC records, XSLT can be bypassed for increased
1013 performance with the alternate "MARC map" format. Provide the
1014 path of a file with extension ".mmap" containing on each line:
1016 <field> <subfield> <metadata element></programlisting>
1023 To map the field value specify a subfield of '$'. To store a
1024 concatenation of all subfields, specify a subfield of '*'.
1029 <term>pz:authentication</term>
1032 Sets an authentication string for a given server. See the section on
1033 authorization and authentication for discussion.
1038 <term>pz:allow</term>
1041 Allows or denies access to the resources it is applied to. Possible
1042 values are '0' and '1'.
1043 The default is '1' (allow access to this resource).
1044 See the manual section on authorization and authentication for
1045 discussion about how to use this setting.
1050 <term>pz:maxrecs</term>
1053 Controls the maximum number of records to be retrieved from a
1054 server. The default is 100.
1062 This setting can't be 'set' -- it contains the ID (normally
1063 ZURL) for a given target, and is useful for filtering --
1064 specifically when you want to select one or more specific
1065 targets in the search command.
1070 <term>pz:zproxy</term>
1073 The 'pz:zproxy' setting has the value syntax
1074 'host.internet.adress:port', it is used to tunnel Z39.50
1075 requests through the named Z39.50 proxy.
1081 <term>pz:apdulog</term>
1084 If the 'pz:apdulog' setting is defined and has other value than 0,
1085 then Z39.50 APDUs are written to the log.
1094 This setting enables
1095 <ulink url="&url.sru;">SRU</ulink>/<ulink url="&url.solr;">SOLR</ulink>
1097 It has four possible settings.
1098 'get', enables SRU access through GET requests. 'post' enables SRU/POST
1099 support, less commonly supported, but useful if very large requests are
1100 to be submitted. 'srw' enables the SRW (SRU over SOAP) variation of
1104 A value of 'solr' anables SOLR client support. This is supported
1105 for Pazpar version 1.5.0 and later.
1111 <term>pz:sru_version</term>
1114 This allows SRU version to be specified. If unset Pazpar2
1115 will the default of YAZ (currently 1.2). Should be set
1116 to 1.1 or 1.2. For SOLR, the current supported/tested version is 1.4
1122 <term>pz:pqf_prefix</term>
1125 Allows you to specify an arbitrary PQF query language substring.
1126 The provided string is prefixed the user's query after it has been
1127 normalized to PQF internally in pazpar2.
1128 This allows you to attach complex 'filters' to queries for a given
1129 target, sometimes necessary to select sub-catalogs
1130 in union catalog systems, etc.
1136 <term>pz:pqf_strftime</term>
1139 Allows you to extend a query with dates and operators.
1140 The provided string allows certain substitutions and serves as a
1142 The special two character sequence '%%' gets converted to the
1143 original query. Other characters leading with the percent sign are
1144 conversions supported by strftime.
1145 All other characters are copied verbatim. For example, the string
1146 <literal>@and @attr 1=30 @attr 2=3 %Y %%</literal>
1147 would search for current year combined with the original PQF (%%).
1153 <term>pz:sort</term>
1156 Specifies sort criteria to be applied to the result set.
1157 Only works for targets which support the sort service.
1163 <term>pz:recordfilter</term>
1166 Specifies a filter which allows Pazpar2 to only include
1167 records that meet a certain criteria in a result.
1168 Unmatched records will be ignored.
1169 The filter takes the form name, name~value, or name=value, which
1170 will include only records with metadata element (name) that has the
1171 substring (~value) given, or matches exactly (=value).
1172 If value is omitted all records with the named metadata element
1173 present will be included.
1179 <term>pz:preferred</term>
1182 Specifies that a target is preferred, e.g. possible local, faster
1183 target. Using block=pref on show command will wait for all these
1184 targets to return records before releasing the block.
1185 If no target is preferred, the block=pref will identical to block=1,
1186 which release when one target has returned records.
1192 <term>pz:block_timeout</term>
1195 (Not yet implemented).
1196 Specifies the time for which a block should be released anyway.
1202 <term>pz:facetmap:<replaceable>name</replaceable></term>
1205 Specifies that for field <replaceable>name</replaceable>, the target
1206 supports (native) facets. The value is the name of the
1207 field on the target.
1211 At this point only SOLR targets have been tested with this
1218 <varlistentry id="limitmap">
1219 <term>pz:limitmap:<replaceable>name</replaceable></term>
1222 Specifies attributes for limiting a search to a field - using
1223 the limit parameter for search. In some cases the mapping of
1224 a field to a value is identical to an existing cclmap field; in
1225 other cases the field must be specified in a different way - for
1226 example to match a complete field (rather than parts of a subfield).
1229 The value of limitmap may have one of two forms: referral to
1230 an exisiting CCL field or a raw PQF string. Leading string
1231 determines type; either <literal>ccl:</literal> for CCL field or
1232 <literal>rpn:</literal> for PQF/RPN.
1236 The limitmap facility is supported for Pazpar2 version 1.6.0.
1242 <varlistentry id="pzurl">
1246 Specifies URL for the target and overrides the target ID.
1250 <literal>pz:url</literal> is only recognized for
1251 Pazpar2 1.6.4 and later.
1257 <varlistentry id="pzsortmap">
1258 <term>pz:sortmap:<replaceable>field</replaceable></term>
1261 Specifies native sorting for a target where
1262 <replaceable>field</replaceable> is a sort criteria (see command
1263 show). The value has to components separated by colon: strategy and
1264 native-field. Strategy is one of <literal>z3950</literal>,
1265 <literal>type7</literal>, <literal>cql</literal>,
1266 <literal>sru11</literal>, or <literal>embed</literal>.
1267 The second component, native-field, is the field that is recognized
1272 Only supported for Pazpar2 1.6.4 and later.
