3 Added implementation-codes directive for .mar files.
5 Avoid error for missing recordId when zebraidx' option -s is in use.
7 Fixed problem with some disk blocks not beeing freed correctly when
8 'drop database' is used.
12 Facets can now be performed on sort registers (:s), not just regular indexes
13 (:w, :p) etc.. The performance appers to be much better than before.
15 Added a facility to embed metadata for records generated by the DOM XML
16 filter. The meta data step is triggered by a 'process-meta' section in the
17 retrieve section of the dom config, e.g.
18 <retrieve name="myelementset">
19 <xslt stylesheet="my-usual.xsl"/>
22 The meta section substitutes metadata for all elements called 'meta' in
23 namespace http://indexdata.com/zebra-2.0 . The meta element must have
24 exactly one attribute, name, which specifies the special
25 element set name which is equivalent to the suffix to zebra:: for
26 non-embedded special retrievals. This allows snippets, facets etc to be
29 Fixed bug #2202: incorrect sorting order when searching multiple databases.
37 Changed service name for Windows. Bug #978.
39 Fixed the alwaysmatches including _ALLRECORDS for ICU term indexing. Bug #2139.
43 Handle right-truncation for ICU normalized terms.
45 Updated OAI-PMH example.
49 Fixes for searches on Chinese text.
51 Fixes for scan using ICU indexing terms.
55 Fixed some memory violations for ICU enabled indexing that could be
56 triggered by long phrases.
58 Enable ICU on Windows. Thanks to Tumer Garip for makefile patches.
60 Fixed bug #2002: Zebra crashes during merge using ICU indexing.
64 Handle encoding errors for strings passed to ICU. (assert was
67 Added zebraidx command, adelete, which attempts to delete records.
68 It's like 'delete', but does not fail if a record does not exist.
72 Added experimental support for faceted results. This is implemented
73 as a special retrieval on a result set and is triggered using element
74 set name zebra::facet::f1:t1,f2,t2,.. which will return terms and
75 hit counts for field f1, type t1, field f2, type t2, .. The returned
76 data is packed as XML or SUTRS depending on record syntax.
78 Added support for Unicode-based indexing using ICU. This allows
79 locale specific scanning, sorting. The implementation is based on
80 the ICU utility part of YAZ 3.0.16 and later. See the manual as well
81 as the examples/marcxml for an example of the use of ICU.
85 Fixed bug with scan and staticrank enabled. Bug introduced in 2.0.16.
89 Scan now returns a displayTerm which closer to the original word/phrase
92 Added snippet support. Element set name zebra::snippet will make
93 Zebra return an XML record with snippets (terms around matching terms).
95 Fixed bug #1142: Non-indexed but listed attributes issues diagnostic.
97 Fixed bug #1131: Missing value-of data in DOM filter.
99 Fixed bug #1049: zebra.cfg lines with leading space are ignored.
101 Fixed bug #1128: sortmax not honored.
103 Fixed bug #1121: Crash for some searches with customized string.chr.
105 --- 2.0.14 2007/05/09
107 Zebra uses the YAZ 3 API. Note that this changes the Zebra API
108 as well. The register layout is the same however.
110 Fixed bug #1114: scan within set may use excessive CPU.
112 Fixed memory leak that occurred in scan.
114 Fixed memory leak that occurred for each deleted record.
116 Optimize updates of records where content is almost identical to previous
117 version of record. This makes updating of the internal explain database
120 For RPN queries the index type (w,p,..) may be specified verbatim as
121 structure attribute with string value, e.g. @attr 4=w .
123 Changed record update API . It is now handled by function
124 zebra_record_update which does insert/replace/delete/update of records .
125 This function replaces zebra_record_{insert,delete} and
126 zebra_admin_exchange_record. The DOM filter uses this feature and the
127 @type attribute in record element specifies the action
128 insert/replace/delete/update.
130 Added support for multi-record updates (Bug #944). Based on patch from
133 --- 2.0.12 2007/03/07
135 Fixed bug with indexing of attributes for rec.grs-class of filters.
136 If X-Path was enabled xelm a/@b would be ignored.
138 Fixed bug in register system where 'no more space' messages was produced
139 even though there was plenty of space.
141 Fixed bug #884: Entity declarations in input are lost at retrieval time.
143 Implemented new filter 'dom'. See test/xslt/dom-config*xml for examples.
144 This, like alvis, performs indexing and retrieval using XSLT. But Unlike
145 alvis, it allows multiple XSLT steps to be performed and does ISO2709
148 --- 2.0.10 2007/01/24
150 Staticrank indexing is now an index register type defined in default.idx
151 via directive 'staticrank'. The 'staticrank' directive for grs is no longer
152 supported (was only implemented for Zebra 2.0.8).
154 For searches, allow truncmax value to be controlled with attribute 13.
155 If given, that overrides the value of 'truncmax'.
157 For truncations being limited (abort at truncmax terms), zebrasrv returns
158 SearchResponse with resultSetStatus=subset.
160 For estimated hit counts, zebrasrv returns SearchResponse with
161 resultSetStatus=estimate.
165 For searches, do not truncate more than at most 'truncmax' terms in one
166 single term with right-truncation/regular attribute. By default, 'truncmax',
169 Bug #781: Easier tracking of result sets. We only do this when mkstemp
170 is available (most moderun Unixes supports this). The PID is included
171 in filename : tempdir/zrs_PID_XXXXXX.
173 Added support for specification of staticrank for grs-class of filters.
174 This is enabled by using 'staticrank indexname' in .abs. Contents of
175 indexname (elm ... indexname:w) is then used as value for staticrank.
177 Implemented sorting via the ISAMB system. To enable, use sortindex:i in
180 Added special retrieval support for sort keys. These keys can also be
181 fetched using zebra::index:field:s
183 Added support for specification of approximative limits for whole query.
184 This is specified as attribute type 12. Semantics is the same as
185 estimatehits in zebra.cfg.
189 Fixed bug #736: Updates gets slower.
191 Fixed bug #735: Delete fails to process rest of file after a record that
194 Added RPM package for Zebra 2.
196 Improved indexing speed for large documents.
198 Added support for special utility retrieval zebra:: which offers retrieval
199 of fundamental properties for record, such as indexed terms, raw record,
200 and system record ID.
204 Fixed bug #47: Commit needs to check for roll-back.
206 Fixed bug #672: Trailing characters in password are ignored
208 Added extra presence check for tcl.h, because some systems have
209 tclConfig.sh installed even though Tcl C headers are missing.
211 Optimized melm performance.
213 Do not use sync(2) during commit (but rely on sync'd individual files).
215 Fixed bug in ISAMB's utility function decode_ptr. With gcc -O3 on some
216 platforms the src argument was not updated. Problem was compiler
217 optimization due to strict aliasing rules.
221 Bug fixes: #638, #647, #657, #669.
223 Implement skip of 0 hit counts in scan. Useful for scan operations
224 limited by a result set.
226 Honor position attribute, i.e. allow first-in-field search. To
227 enable this, "firstinfield 1" must be given for an index in
228 default.idx. Enabled in tab/default.idx for w. At this stage
229 first-in field is supported for phrase/and-list/or-list searches
231 Common stream reader interface for record filters (struct ZebraRecStream).
233 Debian package fix: packages idzebra-2.0 + libidzebra-2.0-modules did
234 not depend properly on sub packages.
238 New record filter (record type) 'alvis' which uses XSLT transformations
239 to drive both indexing as well as retrieval. See example configuration in the
240 'example/alvis-oai' directory.
242 'isamb' is now the default ISAM system. In Zebra 1.3, the default ISAM was
243 'isamc'. The type used can still be configured with the 'isam' setting
246 Index structure is now 64-bit based, also on 32 bit systems.
247 There are no more 2GB register file limits.
249 Extended search result tuning. Approximate limit for terms can be enabled
250 and specified with attribute 11. The (approx or exact) hit count is returned
251 as part of the search response as in 1.3 series. The subqueryID of a search
252 term hit count can be specified with attribute 10.
254 Zebra uses string attributes for indexing internally. Using set+numeric
255 use attribute can still be used. This is a search-only conversion which
256 inspects '*.att'-set files as indicated using attset-directives in 'zebra.cfg'.
257 'attset' references are no longer required, but when used they deserve
258 as "check" for that the index names used are also present in '*.att'.
260 Zebra record filters (record type handlers) may be built as loadable
261 modules (.so's) on Unix. In particular the Zebra 2.0 Debian package uses
262 separate packages for each of them. This also means that zebra programs
263 such as zebraidx is no longer depending on Tcl/other..
265 Documentation updates, especially on query structure and syntax, SRU,
266 XSLT support, alvis filter module, and many added examples.
268 Improved logging of the 'zebrasrv' and 'zebraidx' binaries.
270 Improved debian package structure.
