3 New target setting: pz:authentication_mode. PAZ-896
5 pazpar2 PRM: pazpar2 runs as user nobody. PAZ-893
7 Strip #-suffix for ZOOM URLs. PAZ-892
11 Fix issue with hanging show/bytarget. Could happen if new search was
12 fired with filter before show from previous show completed.
14 Add 'date' handling for solr-pz2.xsl.
18 pz:authentication may carry user group password. If pz:authentication
19 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
20 authentication. Two forms are allowed
23 If no blanks are present, open authentication is in use (as before).
25 Fix {prev,next}recid elements that are returned by record
26 command. These were incorrect in versions 1.6.23 thru 1.6.32.
30 Experimental support for snippets. If argument snippets=1 is given
31 for command record or show, the text will include <match>-tags for
32 those area that matches.
34 Fix memory leak WRT client structures (incorrect inc ref count).
36 Log when a HTTP response is serialized and the time elapsed.
38 New command, service, which returns current service XML in use for
43 Local limit for fields of type "generic" (ie text fields) are
44 now normalized by mergekey rule before comparison takes place.
45 Before, no normalization took place and comparsion was, thus, exact.
47 New facility: dynamic rank , which allows ranking to be changed
48 for an existing result set. The rank can be set for search or
49 show. This overrides the rank for metadata elements (which fields
52 New facility:dynamic mergekey , which allows mergekey to be changed
53 for an existing result set. The mergekey can be set for search or
56 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
57 Also, allow ports to be given as names (not just integers).
58 Fix @-notation on systems that don't support IPV6 sockets.
62 Add MasterKey Connect configuration. Refer to section "non-standard
63 databases" for more information.
65 Allow timeformat for log to be specified with option -m (as Metaproxy
68 New Debian package pazpar2-dbg.
70 Fix NULL ptr reference of se->relevance. If a new search is initiated
71 and a CCL query fails to parse, Pazpar2 could crash.
73 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
74 existed in 1.6.29 only.
78 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
79 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
80 changed by setting "host" attribute for the "listen" element.
82 Change semantics of pz:extendrecs. Allow for repeated fetches .
83 pz:extendrecs is now the number of extra records to fetch (was total
88 Fix hang or memory violation if show occurred before a search. (not that
89 it makes much sense to perform a show before a search).
93 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
98 New pz:metadata attribute, empty="empty-value" for Pazpar2's
99 internal representation. With this attribute, Pazpar2 treates an empty
100 pz:metadata type as having the value for "empty" - if empty.
102 New setting, pz:extendrecs, which triggers extended fetch of records
103 for a database beyond pz:maxrecs for a show command.
105 Fix warning that was falsely issued for "missing limitmap".
107 Log message for Pazpart start/stop changed. Now using same style as
108 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
110 --- 1.6.25 2013/02/07
112 Fix hang of 2nd command=show with esn/syntax given.
114 --- 1.6.24 2013/01/18
116 New merge attribute type: 'first', which takes all metadata fields
117 from first target that returns the particular field.
119 --- 1.6.23 2013/01/02
121 Extend info command with hostname and YAZ SHA1
122 Indent results for both command stat and info.
124 Allow limit on merged content. The new configuration metadata
125 element, limitcluster, configures that a metadata element (name) be used
126 as limit name for search. Applies to the whole service (ie all targets),
127 unlike pz:limitmap which is configured per-target (database).
129 New feature: limitmap local:* matches against all metadata fields.
131 Allow repeated list in limitmap spec . Separated by comma. For
132 example: value="local:title,rpn:@attr 1=4".
134 New element <message> in bytarget response. Holds diagnostic message
135 of code (say 'Unsupported Use Attribute' for Bib-1 114).
137 Improved logging for record ingestion failures.
139 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
140 when YAZ is compiled without ICU support.
142 --- 1.6.22 2012/10/11
144 Requires YAZ-4.2.40 to support native solr support.
146 Fix and improve logic handling whether or not to re-do search on sort
147 order changes. A sort order with change in ascending/descending only
148 whould not trigger a new search, which is required for targets with
149 native sorting capabilities. Each client is now checked if instructions
150 (sortmap) exist for native sorting and only client that does requires
151 it is researched. Other clients is just re-ingesting the records,
152 they already have. The resultset is now cleared if any researching
155 Connection sharing between session has broken since version 1.6.8 with
156 introduction of logic that would minimize searching if pazpar2 could
157 detect this based on same query and limits and partly sort order.
158 This could lead to segementations violations.
160 Added a chapter in the manaul about relevance ranking.
162 --- 1.6.21 2012/09/24
164 Rank tweak: follow=number will increase mult by number if two terms
165 occur next to each other; number-1 if they are one term apart , .. 0
166 if they are number a part (all in order). Default is 0 (following
167 terms has no effect).
169 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
170 value given by lead and l is length from beginning of field where
171 term occurs (l=0 for first term, l=1 for second term, ..). Default
174 Rank tweak: length=strategy. length="linear" if mult is to be divided
175 by length (existing, default behavior), length="log" if mult is to be
176 divided by log2(1+length), length="none" if mult is not to be affected
179 --- 1.6.20 2012/09/21
181 Rank algorithm details may be printed as part of show response in
182 element <relevance_info>.. This is only printed if <rank debug="yes"/>
185 Record as returned by show/record command have a minimal indentation
186 which makes things human-readable.
188 New configuration of default sorting criteria (sort-default) in
189 service definition. If no criteria is defined it will be as before
192 Search command now supports sort parameter just as the show command.
193 If no parameter is give, it will use the service sort-default value.
195 --- 1.6.19 2012/09/18
197 Rank algorithm skips strings that gets normalized to empty string.
198 For example, & and ! could map to the empty string. The weight for
199 those terms is now 0 (as if they were not part of the query).
201 Rank algorithm does not use CCL from limitmap; only from the query
202 parameter (user query).
206 --- 1.6.18 2012/09/17
208 Rank algorithm configurable by 'rank' element inside service. So far
209 only, attribute 'cluster' is recognized. If cluster="yes", multiple
210 records inside a cluster boosts higher than single records. This
211 is default behavior and existing behavior. cluster="no" takes the
212 average score of each record in a cluster.
214 --- 1.6.17 2012/09/05
216 Fix bad re-use of connections (connections with changing proxy should not
219 --- 1.6.16 2012/08/22
221 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
222 resultset and sorting when the sort order is position. However this will be done on
223 every client poll, which will make pazpar2 continuing reset and fetching.
224 It should only be done on FIRST request where the sort order change.
226 Fix an issue on suggestion option: Also disable suggestions on empty string.
228 Clean up in turbo marc stylesheet.
230 Remove the hardcoded size of termlists.
232 --- 1.6.15 2012/06/27
234 New facility: ccldirective may be given in service definition. Allows
235 CCL parsing to be customized a bit, such as defining names of operators
238 New facility: raw record by checksum, rather than offset. The record
239 command optionally takes checksum which identifies certain record from
242 New facility: per field ranking. Rank may be given as M [F N] where
243 M is default rank and N is rank for CCL terms from field F.
245 --- 1.6.14 2012/06/04
247 Fix for IE7/8 in pz.js
249 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
251 Lower log level some places.
253 Remove some invalid test results.
255 --- 1.6.13 2012/05/23
257 Introducing a version=2 parameter for show, termlist and bytarget commands.
258 This enables pazpar2 to return approximation on hit and count count when
259 doing record filtering using the limit parameter on search and a
260 limitmap with a value of "local:"
262 Setting pz:xslt may embed local XSLT as an alternative to referring
264 Value is not CDATA but XML nodes embedded, so escaping is not necessary
265 but a root element *must* be present. For example:
266 <settings target="target="z3950.indexdata.com/marc">
275 Metadata field rank may given by XML internal document (pz:xslt
276 result). If rank is not given, the rank from service description is
279 Metadata field can now configured a default limitmap and facetmap.
280 Setting limitmap to "local:" would work for all kind of targets, but would
281 prob. not be the optimal solution. But at least better than the default behavior
282 of pazpar2 where no filtering is done.
284 A service definition can now also contains <set/> that defines service-wide
285 settings. These will override server-wide sets and will be overridded by
288 New setting, pz:present_chunk, that specifies number of records to fetch
289 at a time. Zero will disable chunkation; will fetch max_records at once.
291 --- 1.6.12 2012/03/14
293 Revert the format change in termlist response, that could break
294 some clients / UIs since they were expecting an (empty) element
295 if no facet values was found.
297 --- 1.6.11 2012/03/07
299 Revert the behavior of returning errors when unable to block
300 on termlist, bytarget and search, when unable to block due to
301 other block. The client will now receive a regular response,
302 but it will be logged in the server. A parameter (report) is
303 added to change behavior to return error response or WARNING
304 status message. Consider this "API" as private, as it is mostly
305 untested and could be changed in future releases.
307 Fix spell error in pz2.js fix in 1.6.10.
309 New Marc2TurboMarc.xsl (contribution from Sven Porst).
310 Can solve the missing marc21.xsl updates in some cases.
312 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
313 substring (contribtion from Sven Porst)
315 marc21.xsl: fix 1-based substring call
317 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
319 Add test_termlist_block to test suite
321 --- 1.6.10 2012/02/23
323 Fix SEGV for invalid PQFs and SRU/SOLR targets
324 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
326 Fix pz2.js: "null object" due to change in in bytarget result XML.
328 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
329 Added this normalization to the other subject-long fields (d6xx),
330 where it was missing.
332 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
333 Still differences around medium and holdings. marc21.xsl is not
334 longer active used by Index Data, and should be considered unsupported.
335 Use tmarc.xsl instead.
339 Fix SEGV that could occur for failed connections.
343 Fix bug for command sort that could return no results for active clients
344 (from previous search). This bug was present in 1.6.6-1.6.7.
346 Fix bug in results that could include results that should have been
347 filtered out. This bug was present in 1.6.6-1.6.7.
351 Fix bug introduced in 1.6.6 where a connection re-use could stall
354 Local filtering may now specify a local metadata field, eg.
355 pz:limitmap:somefield[t]=local:otherfield
359 For search, when limit and or filtering is in place and search
360 is identical to previous search, the result set is re-used and the
361 target is not searched.
363 Limits may work perform local filtering as well, by using "local:"
368 Updated bytarget command to contain a suggestions element with misspelled
369 words and suggestions to these. pz2.js has been updated to deliver this
370 onwards as well. Only target that currently delivers this is the solr
371 client in YAZ 4.2.18.
375 New service definition element, xslt, that allows an embedded stylesheet
376 to be defined. This can be referred to from pz:xslt as an alternative to
379 New pz:sortmap:field setting for specifying hints on how to make
380 a target natively sort on a field. This is used for command=show in
381 conjunction with sort.
383 New pz:url setting for specifying the actual URL for a target. When
384 this is used the target ID is not used as URL anymore and the target ID
385 may be almost any string (not including []).
387 command=termlist without name parameter returns all termlists/facets.
388 Previously if name parameter was omitted, only "subject" was returned.
392 Make termlist sorting stable. Terms with same frequency are now sorted by
393 their display name. This makes a pretty display and improves our
394 regression test because qsort is not a stable sort.
396 New sort parameter value 'position'. The 'position' sorts merged records
397 by their original position from the remote target. This is primarily useful
398 for debugging and may be used for targets that already perform some kind
399 of relevance ranking. Note that sort by default is decreasing; so to get
400 records in their original order sort=position:1 must be used.
404 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
406 Facility to change working directory for pazpar2 daemon. Option -wdir
407 sets working directory to dir. This facility is useful if core dumps
408 must be saved. In this case, the current working directory must be
409 writable by the running user, such as "nobody".
413 New configuration element <icu_chain> for <server>/<service> which
414 allows a named ICU rule (chain) to be defined. The names relevance,
415 sort, mergekey and facet are used for those operations. The definition
416 <icu_chain id="sort" locale="en"> .. </icu_chain>
418 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
419 And so on.. for relevance, mergekey and facet as well. The latter
420 style is deprecated. The facet terms are normalized by the facet
421 rule by default. This may be changed on a metadata field basis by
422 defining the new attribute 'facetrule' for the metadata element.
424 <icu_chain id="myrule" locale="en"> ... </icu_chain>
425 <metadata name="author" termlist="yes" facetrule="myrule"/>
427 Preserve rorder for merged metadata. Fixes issue as reported by Sven
428 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
430 tmarc.xsl: set journal-subpart to 773$ only.
434 Modify the behavior for the limit parameter (first defined in 1.5.7).
435 Mapping of limit searches are now defined by the new configuration item
436 pz:limitmap. Fix a dead-lock problem with the limit parameter.
438 Extend tmarc.xsl to extract 773$g data (OpenURL).
442 ICU default maps remove backquote (`).
444 Command 'search' takes limit parameter (optional). The limit parameter
445 allows a search to be limited one or more facets and the corresponding
446 values. This is for server side filtering.
448 Configure tweak: Use -lm for log(3) if needed
452 Fix a problem with skiparticle sortkey that could be completely
453 ignored (and reduced to "").
455 Fix dependency problem in pazpar2 RPM package (did not require
456 libyaz4 as it should).
460 Fix memory leak that occurred for command=termlist&name=xtargets .
462 Pazpar2 may save HTTP requests. Enabled by option -R.
466 Experimental support for DTIC DADS target. New dads-pz2.xsl.
468 Support for query_syntax (overrides the default for SRU | Z39.50)
470 Support for extraArgs (ZOOM "extraArgs" option) for targets
472 New commands: status-server and status-session
476 Fix for threaded runs: Client now have a copy of the database URL,
477 which can used after the database has been release from the client.
478 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
480 tmarc.xsl: Add journal-title-abbrev and full text.
482 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
484 Fix for cmd=record before search.
486 Session Logging clean up.
488 Fix wrong termlist factor when maxrecs is different from 100.
492 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
493 Term factor is default enabled but can be diseabled by
494 pz:termlist_term_factor=0
498 Add scaling of facet count. Currently always enabled, needs fixing.
499 Allow user-defined info for target suffix. This has no meaning in
500 Pazpar2 except to distinguish targets from each other. The suffix
501 data begins with #. For example z3950.indexdata.com/gils#Mydata
503 Added exact-match recordfilter; format name=value
507 SOLR support. Pazpar2 may operate as web service client for SOLR.
511 Fix for show command and block=1 (dead lock). Bug was introduced in
516 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
517 tested on CentOS 5.5 only.
521 Fix problem with result sets being removed from a client session
522 if the connection for it was resused by another session. Bug #3489.
524 New iphone UI for Pazpar2 (www/iphone).
528 Fixes for threaded operation.
530 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
532 New example services in etc/services in source. In the Debian packages
533 these are located in /etc/pazpar2/services-available
535 Threaded mode operational on Windows. Requires Windows 7 or Windows
538 Default value of setting pz:max_connections is 0 which means that there
539 is no limit on number of connections.
543 Pazpar2 may operate in threaded mode. Enabled by element threads in
544 the configuration. See pazpar2_conf for details.
546 New setting setting: pz:max_connections. Setting pz:max_connections is
547 a limit of number of sockets to a host. When this limit is reached,
548 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
549 The client will be marked Client_Error when it can not be searched
550 (other clients in a session may work). If pz:max_connections is not set
551 for a target, a value of 30 will be used. Note: the pz:max_connections
552 will only work in threaded mode.
554 pz2.js: JSON support for show.
556 Debian package: Enable default service, default.xml, before starting
557 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
561 Debian version depends on on libyaz4. Note that Pazpar2 will still
562 compile from source with YAZ 3.
564 Split services into separate files. The example configuration file
565 pazpar2.cfg.dist now includes a default service default.xml (part of
566 etc). And default.xml includes settings/edu.xml. The default.xml file,
567 not to be confused with settings/defaults.xml, is a template for jsdemo
568 and other services. The Debian package installs /etc/pazpar2/server.xml
569 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
570 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
571 The default.xml (from etc) is installed in /etc/pazpar2/services-available
572 and a symlink to it is created from services-enabled. The default.xml
573 service is unnamed and, thus, will be used by jsdemo and test1.
575 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
576 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
580 Support for additional fields in cf.xsl and pazpar2.conf.dist:
581 publisher, available, due, location (=locallocation), callno
582 (=callnumber), thumburl and score.
584 Describe pz:xslt and the auto setting.
586 Move mergekey definition away from the normalization stylesheets and
587 define a mergekey common for all target types in pazpar2.cfg.
589 Code update: Use the Odr_int type for hit counts. This is part of
590 YAZ 3.0.47 and later and so configure checks for that.
594 Metadata attribute 'skiparticle' also works for ICU based
595 normalization. (was only working for the non-ICU/ASCII before).
597 Command bytarget with argument settings=1 will show settings per
598 target.. This is to be able to verify correct settings and be able to
599 test that they are correct. The database settings array size is now
600 also stored.. Problems with database settings array is that if not
601 careful it will be too small (smaller than dictionary per-service
604 Make record list sorting stable by comparing mergekey for records if
605 relevance/title or other sorting criteria all match. This is merely to
606 ensure that our regressions tests works (reproducible output).
608 Relevance calculation changes: use a different denominator (length) for
609 per-field relevance scoring.. Instead of length of all ranked fields we
610 now use length of individual fields (as if they were individual "free"
611 text fields). This will ensure that documents with a long field with no
612 match (say description) will not "hurt" a title match.
614 Diagnostic member was not set on connection error. Fixed
618 Command search takes two optional parameters, startecs and maxrecs,
619 that specifies the start offset (0, 1, ...) and maximum number of records
620 to fetch for each target.
622 XSLTs + MARC maps are cached within a session so we don't re-parse
623 them over and over again. Even for a session with a single search
624 there's much to be gained because many targets use the same
627 The metadata attribute 'mergekey' now takes one of three values 'no',
628 'required', 'optional' . And the resulting mergekey from metadata
629 is now ordered in the same way as metadata in the service definition.
630 Older Pazpar2 version use the order in which metadata appeared in a
633 The search argument 'filter' now offers a new operator ~ which does a
634 substring match. The = operator works as before: string match for
635 anything but pz:id, or target match for pz:id.
637 New setting pz:recordfilter. The value of this setting takes the
638 form name[~value]. This setting makes Pazpar2 ignore all retrieved
639 records that do not have the metadata element name with value substring
642 Pazpar2 allows YAZ log level to be set (option -v).
646 For WS responses Pazpar2 creates XML header. Exception: raw record.
648 Setting XML files are now stored in etc/settings instead of etc. This
649 reflects the layout with the Debian package layout.
651 Settings may be posted for command=settings. The POSTed settings must
652 have root element 'settings' like regular setting files. In order to be
653 recognized, the POST request must use Content-Type=text/xml.
655 A service may be posted for command=init. This service will be used
656 during the session. The service may have its own target settings,
657 ICU config, timeout, etc. In order to be recognized, the POST request
658 must use Content-Type=text/xml.
660 Timeout values may be given per-service. That's element 'timeout'
661 which takes three attribute values (a subset may be given): 'session',
662 'z3950_operation', 'z3950_session'. Option -T is no longer supported
663 - used to specify session timeout.
665 Option -t tests the Pazpar2 configuration and returns exit code
666 (0=success, non-zero=failure). In previous version of Pazpar2, -t
667 specified local settings.
669 In version 1.2.0 the configuration file - after include processing -
670 was dumped to stdout. Now, the configuration is only dumped to the
671 yaz log file if option -d is given.
675 Configuration may now have multiple server areas. This means that a
676 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
677 yet supported - on a server basis. Configuration may also have multiple
678 services .. That is repeating service elements inside a server. Each
679 has an attribute 'id' which serves as service ID. This ID in turn may
680 be used in a Pazpar2 session, by specifying parameter service=ID for
681 command init. There can be at most one unnamed service inside a server
682 which can be referred to by not specifying an service ID for command
683 init (backwards compatible). In order to partition multiple servers and
684 services a new include directive has been added. This takes an attribute
685 'src' which specifies one or more sub-files. For example to include
686 service files, one might use:
687 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
688 It is the intention that that completely makes the settings directive
691 Fix problem where the record command would wait forever if there were
692 no targets to wait for (activeclients == 0).
696 One result set is created per session (last search) rather than for
697 each connection which happen to be shared (bug #3009).
699 marc21 stylesheets changed for efficiency.
703 Session timeout may be specified on the command-line as option -T.
705 Pazpar2 may now be operated in a no-merged mode for records.. All records
706 will be considered unique. This mode is enabled if no mergekey is
707 generated by the normalization stylesheet (pz:xslt).
709 Pazpar2 caches original records from each target and the 'record' command
710 with offset returns the original record if 'syntax' and 'esn' are NOT
711 specified. This speeds up retrieval of original records but also means
712 that Pazpar2 uses more memory. The cached records will be freed when the
713 session terminates or a new search is executed.
715 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
716 library part of YAZ is used.
718 Added SRU client support.
720 Automatically computes pz:nativesyntax if not provided. Works for XML and
723 --- 1.0.13 2008/11/24
725 Command bytarget returns name of target (if defined).
727 --- 1.0.12 2008/11/04
729 Fixed bug #2021.. location now holds all brief elements.
731 --- 1.0.11 2008/10/15
733 Fixed check for application/x-www-form-urlencoded parameters.
735 --- 1.0.10 2008/10/14
737 Fixes for IE in pz2.js.
739 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
743 Changed the JS library pz2.js to use POST for long URL (+ params).
745 Added installation instructions for Windows. Note: NT services is
746 NOT available until we make a new release of YAZ.
748 Preserve order of repeated metadata fields (they were reversed before).
750 More MARC21 information extracted for metadata.
754 Fixed bug #1162: HTML entities are not escaped properly.
756 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
760 Marc21 stylesheet updated to reflect multiple full text fields
764 Fixed bug in pz2.js WRT DOMElement attributes on IE.
766 Fixed bug 2100: Database wildcards not working
770 Added support for retrieval of records in binary.
772 Fixed bug 1794: Pazpar2 does not return valid XML.
774 Deal with ICU not returning sortkey (resulted in SEGV before).
778 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
779 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
781 Improved diagnostics when Pazpar2 HTTP decoding fails.
783 Pazpar2 requests may be POSTed as using Content-Type
784 application/x-www-form-urlencoded.
786 Pazpar2 honors LF in HTTP headers.
788 Handle targets that handle negative hit counts (should not happen, but it
793 ICU is used for tokenization and normalization of the following: mergekey,
794 sorting, relevance terms.
796 Debian package now enables ICU tokenization and normalization by default.
800 Exposed user setting values (i.e. non-pz: names) to the record systems in two
801 ways: Either as parameters to the normalization stylesheets (which would allow the
802 programmer to postprocess or use the values in any way) or after the normalization
803 step, in which case values are made part of the normalized record (and available for
804 sorting, termlists, display, or other interface-related use.
806 Implemented sorting by year.
808 Option -d dumps records to the current log file instead of stderr.
810 Fixes for compilation on cygwin.
812 Z39.50 client code uses pz:elements. pz:elements was recognized in
813 earlier Pazpar2 versions but it was not used for anything.
815 icu_chain_test is using fgets instead of getline - fixes compilation
818 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
819 query conversions fail (rather than _any_). This means targets that do
820 not support some fields are ignored in a search.
824 Improved handling of socket timeout for Z39.50 connections.
826 Misc documentation updates and spell fixes.
828 Debian package pazpar2 creates log rotate entry.
830 Debian package pazpar2-apache2 reloads Apache2.
832 jsdemo included in distribution. It illustrates the use of the js/pz2.js
837 First public release.
