3 Changed service name for Windows. Bug #978.
5 Fixed the alwaysmatches including _ALLRECORDS for ICU term indexing. Bug #2139.
9 Handle right-truncation for ICU normalized terms.
11 Updated OAI-PMH example.
15 Fixes for searches on Chinese text.
17 Fixes for scan using ICU indexing terms.
21 Fixed some memory violations for ICU enabled indexing that could be
22 triggered by long phrases.
24 Enable ICU on Windows. Thanks to Tumer Garip for makefile patches.
26 Fixed bug #2002: Zebra crashes during merge using ICU indexing.
30 Handle encoding errors for strings passed to ICU. (assert was
33 Added zebraidx command, adelete, which attempts to delete records.
34 It's like 'delete', but does not fail if a record does not exist.
38 Added experimental support for faceted results. This is implemented
39 as a special retrieval on a result set and is triggered using element
40 set name zebra::facet::f1:t1,f2,t2,.. which will return terms and
41 hit counts for field f1, type t1, field f2, type t2, .. The returned
42 data is packed as XML or SUTRS depending on record syntax.
44 Added support for Unicode-based indexing using ICU. This allows
45 locale specific scanning, sorting. The implementation is based on
46 the ICU utility part of YAZ 3.0.16 and later. See the manual as well
47 as the examples/marcxml for an example of the use of ICU.
51 Fixed bug with scan and staticrank enabled. Bug introduced in 2.0.16.
55 Scan now returns a displayTerm which closer to the original word/phrase
58 Added snippet support. Element set name zebra::snippet will make
59 Zebra return an XML record with snippets (terms around matching terms).
61 Fixed bug #1142: Non-indexed but listed attributes issues diagnostic.
63 Fixed bug #1131: Missing value-of data in DOM filter.
65 Fixed bug #1049: zebra.cfg lines with leading space are ignored.
67 Fixed bug #1128: sortmax not honored.
69 Fixed bug #1121: Crash for some searches with customized string.chr.
73 Zebra uses the YAZ 3 API. Note that this changes the Zebra API
74 as well. The register layout is the same however.
76 Fixed bug #1114: scan within set may use excessive CPU.
78 Fixed memory leak that occurred in scan.
80 Fixed memory leak that occurred for each deleted record.
82 Optimize updates of records where content is almost identical to previous
83 version of record. This makes updating of the internal explain database
86 For RPN queries the index type (w,p,..) may be specified verbatim as
87 structure attribute with string value, e.g. @attr 4=w .
89 Changed record update API . It is now handled by function
90 zebra_record_update which does insert/replace/delete/update of records .
91 This function replaces zebra_record_{insert,delete} and
92 zebra_admin_exchange_record. The DOM filter uses this feature and the
93 @type attribute in record element specifies the action
94 insert/replace/delete/update.
96 Added support for multi-record updates (Bug #944). Based on patch from
101 Fixed bug with indexing of attributes for rec.grs-class of filters.
102 If X-Path was enabled xelm a/@b would be ignored.
104 Fixed bug in register system where 'no more space' messages was produced
105 even though there was plenty of space.
107 Fixed bug #884: Entity declarations in input are lost at retrieval time.
109 Implemented new filter 'dom'. See test/xslt/dom-config*xml for examples.
110 This, like alvis, performs indexing and retrieval using XSLT. But Unlike
111 alvis, it allows multiple XSLT steps to be performed and does ISO2709
114 --- 2.0.10 2007/01/24
116 Staticrank indexing is now an index register type defined in default.idx
117 via directive 'staticrank'. The 'staticrank' directive for grs is no longer
118 supported (was only implemented for Zebra 2.0.8).
120 For searches, allow truncmax value to be controlled with attribute 13.
121 If given, that overrides the value of 'truncmax'.
123 For truncations being limited (abort at truncmax terms), zebrasrv returns
124 SearchResponse with resultSetStatus=subset.
126 For estimated hit counts, zebrasrv returns SearchResponse with
127 resultSetStatus=estimate.
131 For searches, do not truncate more than at most 'truncmax' terms in one
132 single term with right-truncation/regular attribute. By default, 'truncmax',
135 Bug #781: Easier tracking of result sets. We only do this when mkstemp
136 is available (most moderun Unixes supports this). The PID is included
137 in filename : tempdir/zrs_PID_XXXXXX.
139 Added support for specification of staticrank for grs-class of filters.
140 This is enabled by using 'staticrank indexname' in .abs. Contents of
141 indexname (elm ... indexname:w) is then used as value for staticrank.
143 Implemented sorting via the ISAMB system. To enable, use sortindex:i in
146 Added special retrieval support for sort keys. These keys can also be
147 fetched using zebra::index:field:s
149 Added support for specification of approximative limits for whole query.
150 This is specified as attribute type 12. Semantics is the same as
151 estimatehits in zebra.cfg.
155 Fixed bug #736: Updates gets slower.
157 Fixed bug #735: Delete fails to process rest of file after a record that
160 Added RPM package for Zebra 2.
162 Improved indexing speed for large documents.
164 Added support for special utility retrieval zebra:: which offers retrieval
165 of fundamental properties for record, such as indexed terms, raw record,
166 and system record ID.
170 Fixed bug #47: Commit needs to check for roll-back.
172 Fixed bug #672: Trailing characters in password are ignored
174 Added extra presence check for tcl.h, because some systems have
175 tclConfig.sh installed even though Tcl C headers are missing.
177 Optimized melm performance.
179 Do not use sync(2) during commit (but rely on sync'd individual files).
181 Fixed bug in ISAMB's utility function decode_ptr. With gcc -O3 on some
182 platforms the src argument was not updated. Problem was compiler
183 optimization due to strict aliasing rules.
187 Bug fixes: #638, #647, #657, #669.
189 Implement skip of 0 hit counts in scan. Useful for scan operations
190 limited by a result set.
192 Honor position attribute, i.e. allow first-in-field search. To
193 enable this, "firstinfield 1" must be given for an index in
194 default.idx. Enabled in tab/default.idx for w. At this stage
195 first-in field is supported for phrase/and-list/or-list searches
197 Common stream reader interface for record filters (struct ZebraRecStream).
199 Debian package fix: packages idzebra-2.0 + libidzebra-2.0-modules did
200 not depend properly on sub packages.
204 New record filter (record type) 'alvis' which uses XSLT transformations
205 to drive both indexing as well as retrieval. See example configuration in the
206 'example/alvis-oai' directory.
208 'isamb' is now the default ISAM system. In Zebra 1.3, the default ISAM was
209 'isamc'. The type used can still be configured with the 'isam' setting
212 Index structure is now 64-bit based, also on 32 bit systems.
213 There are no more 2GB register file limits.
215 Extended search result tuning. Approximate limit for terms can be enabled
216 and specified with attribute 11. The (approx or exact) hit count is returned
217 as part of the search response as in 1.3 series. The subqueryID of a search
218 term hit count can be specified with attribute 10.
220 Zebra uses string attributes for indexing internally. Using set+numeric
221 use attribute can still be used. This is a search-only conversion which
222 inspects '*.att'-set files as indicated using attset-directives in 'zebra.cfg'.
223 'attset' references are no longer required, but when used they deserve
224 as "check" for that the index names used are also present in '*.att'.
226 Zebra record filters (record type handlers) may be built as loadable
227 modules (.so's) on Unix. In particular the Zebra 2.0 Debian package uses
228 separate packages for each of them. This also means that zebra programs
229 such as zebraidx is no longer depending on Tcl/other..
231 Documentation updates, especially on query structure and syntax, SRU,
232 XSLT support, alvis filter module, and many added examples.
234 Improved logging of the 'zebrasrv' and 'zebraidx' binaries.
236 Improved debian package structure.
