3 Deb/RPM/Win Zebra packages uses libyaz5 (rather than libyaz4). This adds
4 SRU 2.0 support for Zebra.
8 Updates for YAZ 5. Zebra compiles fine with YAZ 4 still.
12 Addx + document zebraidx command "check", which checks consistency of
15 Debian : idzebra-2.0-utils includes init.d script. Includes logrotate as
16 well. The zebrasrv init script listens on port 2100. At this time,
17 zebra.cfg, is not part of the package. Administrator must install or
18 modify $CONFIG to point to a working zebra.cfg.
20 RPM: idzebra-2.0 includes init.d script. Also includes logrotate. The
21 zebrasrv init script listens on port 2100 (IPv4 + IPv6). At this time,
22 zebra.cfg, is not part of the package. Administrator must install or
23 modify $CONFIG to point to a working zebra.cfg.
27 For mod_dom filter, allow type="adelete", which will not treat a failed
28 delete as an error (such as a record ID that do not exist already).
30 Log XML2/XSLT errors to yaz_log instead of stdout/stderr.
32 Relay \-character in non-regexp searches. Was treated as backslash
37 Improve hit estimate for or-searches (typically truncation)
39 Fix snippets for non-ICU / seqno not updated.
41 Replace key_compare_it with key_compare. This is because key_compare_it
42 throws exception on some CPUs with alignment constraints.
44 ICU: support @attr 5=2, @attr 5=3 in searches. (left truncation and
45 left+right truncation).
49 Fix problem in dictionary due to increase max size of term.
53 Fix buffer overrun for terms using ICU normalization.
55 Increase max size of indexing term from 256 to 512.
59 Fix a bug in zebra_begin_trans where Zebra could mark a transaction
60 complete when it actually failed. This could happen if register files
65 Scan: allow preferred position > number + 1
67 Fix bug #4592: dict_scan misses
69 Fix snippets for complete fields, bug #4590. The
70 snippet_add_complete_fields (chr-system) now takes the indexing term
71 verbatim and makes that the display term.
75 Utility idebra-abs2dom part of distribution and deb+RPM packages.
77 Fix problem with scan and complete subfields (:p) . In some cases,
78 the display scan terms, would be invalid.
82 RPM: Store libraries in /usr/lib64 on 64-bit platforms.
84 Zebra honors SRU sortkeys. If used with YAZ 4.2.0 or later,
85 CQL sortby is honored as well.
87 Fix scan's handling of normalized terms. Some terms were incorrectly
88 ignored in the scan results, CJK terms in particular.
92 Fix bug in dictionary component of Zebra that could lead to
93 inconsistent register assert for large deleteions.
95 Improve estimate hits for phrase searches.
99 Add Debian package for Ubuntu maverick.
101 Update to newer Libxml2/Libxslt for Windows package.
103 Escape-sequences are disabled for RPN-queries with truncation=105/106.
104 These, unlike regular expressions, do not support \-sequences .
106 --- 2.0.44 2010/06/29
108 grs1: avoid term_len < 0 for .abs operator 'range'
110 ICU: fix use of un-init variable.
112 More reasonable approx hits for truncated searches.
114 Updates WRT Odr_int (YAZ 4).
116 --- 2.0.43 2009/11/05
118 Fix hits counts for searches when @attr 12=n is in use. This bug
119 was introduced in 2.0.40.
121 --- 2.0.42 2009/10/08
123 Proximity modifications. The optimized proximity now deals with more
124 cases, ie all prox of the form @prox 0 d 1 1,2,3 k 2 ..
125 That's exlusive==0, any distance, ordered (true), relation (<, =, <=),
128 Fix bug WRT inconsistent registers, bug #3062.
130 Fix install doc rule so it's compatible with Automake 1.11.
132 --- 2.0.41 2009/08/24
134 Fix typos and other errors in the documentation. Thanks to Galen
137 Fix DOM filter so that full record ID (z:id) if given is used verbatim
138 rather than truncated until first blank - in other words use memcpy
139 rather than sscanf. For PI fix record attributes parsing which was
142 --- 2.0.40 2009/07/13
144 Fixed problem in result set handling and segment handling.
146 --- 2.0.39 2009/07/09
148 Improved speed of record fetching by using a different block sizes
151 Added zlib-compression of recd-storage (record data). This is enabled
152 by using recordCompression: zlib in zebra.cfg.
154 Dictionary delete more agressive (dict_del_string).
156 --- 2.0.38 2009/06/19
158 Improved estimated hits for AND operation (bug #2907)
160 Fixed problem with register area growing after "drop DB". (bug #2913).
162 --- 2.0.37 2009/05/18
164 Example with marc21 is now installed and part of packages.
166 Fixed XSL for OAI example.
168 Fixed problem with generic proximity handling.
170 Added new ranking handler: rank-2. This is a combination of rank-1 and
171 static rank.. The staticrank is inverse (lowest value comes first, etc..).
172 rank-2 thus substracts that from score. This allows a system to specify
173 a "base" rank (=staticrank).
175 --- 2.0.36 2009/02/17
177 Added implementation-codes directive for .mar files.
179 Avoid error for missing recordId when zebraidx' option -s is in use.
181 Fixed problem with some disk blocks not beeing freed correctly when
182 'drop database' is used.
184 --- 2.0.34 2008/11/06
186 Facets can now be performed on sort registers (:s), not just regular indexes
187 (:w, :p) etc.. The performance appers to be much better than before.
189 Added a facility to embed metadata for records generated by the DOM XML
190 filter. The meta data step is triggered by a 'process-meta' section in the
191 retrieve section of the dom config, e.g.
192 <retrieve name="myelementset">
193 <xslt stylesheet="my-usual.xsl"/>
196 The meta section substitutes metadata for all elements called 'meta' in
197 namespace http://indexdata.com/zebra-2.0 . The meta element must have
198 exactly one attribute, name, which specifies the special
199 element set name which is equivalent to the suffix to zebra:: for
200 non-embedded special retrievals. This allows snippets, facets etc to be
203 Fixed bug #2202: incorrect sorting order when searching multiple databases.
205 --- 2.0.32 2008/06/06
209 --- 2.0.30 2008/05/14
211 Changed service name for Windows. Bug #978.
213 Fixed the alwaysmatches including _ALLRECORDS for ICU term indexing. Bug #2139.
215 --- 2.0.28 2008/04/03
217 Handle right-truncation for ICU normalized terms.
219 Updated OAI-PMH example.
221 --- 2.0.26 2008/01/28
223 Fixes for searches on Chinese text.
225 Fixes for scan using ICU indexing terms.
227 --- 2.0.24 2008/01/18
229 Fixed some memory violations for ICU enabled indexing that could be
230 triggered by long phrases.
232 Enable ICU on Windows. Thanks to Tumer Garip for makefile patches.
234 Fixed bug #2002: Zebra crashes during merge using ICU indexing.
236 --- 2.0.22 2007/12/20
238 Handle encoding errors for strings passed to ICU. (assert was
241 Added zebraidx command, adelete, which attempts to delete records.
242 It's like 'delete', but does not fail if a record does not exist.
244 --- 2.0.20 2007/12/19
246 Added experimental support for faceted results. This is implemented
247 as a special retrieval on a result set and is triggered using element
248 set name zebra::facet::f1:t1,f2,t2,.. which will return terms and
249 hit counts for field f1, type t1, field f2, type t2, .. The returned
250 data is packed as XML or SUTRS depending on record syntax.
252 Added support for Unicode-based indexing using ICU. This allows
253 locale specific scanning, sorting. The implementation is based on
254 the ICU utility part of YAZ 3.0.16 and later. See the manual as well
255 as the examples/marcxml for an example of the use of ICU.
257 --- 2.0.18 2007/09/19
259 Fixed bug with scan and staticrank enabled. Bug introduced in 2.0.16.
261 --- 2.0.16 2007/09/12
263 Scan now returns a displayTerm which closer to the original word/phrase
264 from original record.
266 Added snippet support. Element set name zebra::snippet will make
267 Zebra return an XML record with snippets (terms around matching terms).
269 Fixed bug #1142: Non-indexed but listed attributes issues diagnostic.
271 Fixed bug #1131: Missing value-of data in DOM filter.
273 Fixed bug #1049: zebra.cfg lines with leading space are ignored.
275 Fixed bug #1128: sortmax not honored.
277 Fixed bug #1121: Crash for some searches with customized string.chr.
279 --- 2.0.14 2007/05/09
281 Zebra uses the YAZ 3 API. Note that this changes the Zebra API
282 as well. The register layout is the same however.
284 Fixed bug #1114: scan within set may use excessive CPU.
286 Fixed memory leak that occurred in scan.
288 Fixed memory leak that occurred for each deleted record.
290 Optimize updates of records where content is almost identical to previous
291 version of record. This makes updating of the internal explain database
294 For RPN queries the index type (w,p,..) may be specified verbatim as
295 structure attribute with string value, e.g. @attr 4=w .
297 Changed record update API . It is now handled by function
298 zebra_record_update which does insert/replace/delete/update of records .
299 This function replaces zebra_record_{insert,delete} and
300 zebra_admin_exchange_record. The DOM filter uses this feature and the
301 @type attribute in record element specifies the action
302 insert/replace/delete/update.
304 Added support for multi-record updates (Bug #944). Based on patch from
307 --- 2.0.12 2007/03/07
309 Fixed bug with indexing of attributes for rec.grs-class of filters.
310 If X-Path was enabled xelm a/@b would be ignored.
312 Fixed bug in register system where 'no more space' messages was produced
313 even though there was plenty of space.
315 Fixed bug #884: Entity declarations in input are lost at retrieval time.
317 Implemented new filter 'dom'. See test/xslt/dom-config*xml for examples.
318 This, like alvis, performs indexing and retrieval using XSLT. But Unlike
319 alvis, it allows multiple XSLT steps to be performed and does ISO2709
322 --- 2.0.10 2007/01/24
324 Staticrank indexing is now an index register type defined in default.idx
325 via directive 'staticrank'. The 'staticrank' directive for grs is no longer
326 supported (was only implemented for Zebra 2.0.8).
328 For searches, allow truncmax value to be controlled with attribute 13.
329 If given, that overrides the value of 'truncmax'.
331 For truncations being limited (abort at truncmax terms), zebrasrv returns
332 SearchResponse with resultSetStatus=subset.
334 For estimated hit counts, zebrasrv returns SearchResponse with
335 resultSetStatus=estimate.
339 For searches, do not truncate more than at most 'truncmax' terms in one
340 single term with right-truncation/regular attribute. By default, 'truncmax',
343 Bug #781: Easier tracking of result sets. We only do this when mkstemp
344 is available (most moderun Unixes supports this). The PID is included
345 in filename : tempdir/zrs_PID_XXXXXX.
347 Added support for specification of staticrank for grs-class of filters.
348 This is enabled by using 'staticrank indexname' in .abs. Contents of
349 indexname (elm ... indexname:w) is then used as value for staticrank.
351 Implemented sorting via the ISAMB system. To enable, use sortindex:i in
354 Added special retrieval support for sort keys. These keys can also be
355 fetched using zebra::index:field:s
357 Added support for specification of approximative limits for whole query.
358 This is specified as attribute type 12. Semantics is the same as
359 estimatehits in zebra.cfg.
363 Fixed bug #736: Updates gets slower.
365 Fixed bug #735: Delete fails to process rest of file after a record that
368 Added RPM package for Zebra 2.
370 Improved indexing speed for large documents.
372 Added support for special utility retrieval zebra:: which offers retrieval
373 of fundamental properties for record, such as indexed terms, raw record,
374 and system record ID.
378 Fixed bug #47: Commit needs to check for roll-back.
380 Fixed bug #672: Trailing characters in password are ignored
382 Added extra presence check for tcl.h, because some systems have
383 tclConfig.sh installed even though Tcl C headers are missing.
385 Optimized melm performance.
387 Do not use sync(2) during commit (but rely on sync'd individual files).
389 Fixed bug in ISAMB's utility function decode_ptr. With gcc -O3 on some
390 platforms the src argument was not updated. Problem was compiler
391 optimization due to strict aliasing rules.
395 Bug fixes: #638, #647, #657, #669.
397 Implement skip of 0 hit counts in scan. Useful for scan operations
398 limited by a result set.
400 Honor position attribute, i.e. allow first-in-field search. To
401 enable this, "firstinfield 1" must be given for an index in
402 default.idx. Enabled in tab/default.idx for w. At this stage
403 first-in field is supported for phrase/and-list/or-list searches
405 Common stream reader interface for record filters (struct ZebraRecStream).
407 Debian package fix: packages idzebra-2.0 + libidzebra-2.0-modules did
408 not depend properly on sub packages.
412 New record filter (record type) 'alvis' which uses XSLT transformations
413 to drive both indexing as well as retrieval. See example configuration in the
414 'example/alvis-oai' directory.
416 'isamb' is now the default ISAM system. In Zebra 1.3, the default ISAM was
417 'isamc'. The type used can still be configured with the 'isam' setting
420 Index structure is now 64-bit based, also on 32 bit systems.
421 There are no more 2GB register file limits.
423 Extended search result tuning. Approximate limit for terms can be enabled
424 and specified with attribute 11. The (approx or exact) hit count is returned
425 as part of the search response as in 1.3 series. The subqueryID of a search
426 term hit count can be specified with attribute 10.
428 Zebra uses string attributes for indexing internally. Using set+numeric
429 use attribute can still be used. This is a search-only conversion which
430 inspects '*.att'-set files as indicated using attset-directives in 'zebra.cfg'.
431 'attset' references are no longer required, but when used they deserve
432 as "check" for that the index names used are also present in '*.att'.
434 Zebra record filters (record type handlers) may be built as loadable
435 modules (.so's) on Unix. In particular the Zebra 2.0 Debian package uses
436 separate packages for each of them. This also means that zebra programs
437 such as zebraidx is no longer depending on Tcl/other..
439 Documentation updates, especially on query structure and syntax, SRU,
440 XSLT support, alvis filter module, and many added examples.
442 Improved logging of the 'zebrasrv' and 'zebraidx' binaries.
444 Improved debian package structure.
