3 Updates for YAZ 5. Zebra compiles fine with YAZ 4 still.
7 Addx + document zebraidx command "check", which checks consistency of
10 Debian : idzebra-2.0-utils includes init.d script. Includes logrotate as
11 well. The zebrasrv init script listens on port 2100. At this time,
12 zebra.cfg, is not part of the package. Administrator must install or
13 modify $CONFIG to point to a working zebra.cfg.
15 RPM: idzebra-2.0 includes init.d script. Also includes logrotate. The
16 zebrasrv init script listens on port 2100 (IPv4 + IPv6). 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.
22 For mod_dom filter, allow type="adelete", which will not treat a failed
23 delete as an error (such as a record ID that do not exist already).
25 Log XML2/XSLT errors to yaz_log instead of stdout/stderr.
27 Relay \-character in non-regexp searches. Was treated as backslash
32 Improve hit estimate for or-searches (typically truncation)
34 Fix snippets for non-ICU / seqno not updated.
36 Replace key_compare_it with key_compare. This is because key_compare_it
37 throws exception on some CPUs with alignment constraints.
39 ICU: support @attr 5=2, @attr 5=3 in searches. (left truncation and
40 left+right truncation).
44 Fix problem in dictionary due to increase max size of term.
48 Fix buffer overrun for terms using ICU normalization.
50 Increase max size of indexing term from 256 to 512.
54 Fix a bug in zebra_begin_trans where Zebra could mark a transaction
55 complete when it actually failed. This could happen if register files
60 Scan: allow preferred position > number + 1
62 Fix bug #4592: dict_scan misses
64 Fix snippets for complete fields, bug #4590. The
65 snippet_add_complete_fields (chr-system) now takes the indexing term
66 verbatim and makes that the display term.
70 Utility idebra-abs2dom part of distribution and deb+RPM packages.
72 Fix problem with scan and complete subfields (:p) . In some cases,
73 the display scan terms, would be invalid.
77 RPM: Store libraries in /usr/lib64 on 64-bit platforms.
79 Zebra honors SRU sortkeys. If used with YAZ 4.2.0 or later,
80 CQL sortby is honored as well.
82 Fix scan's handling of normalized terms. Some terms were incorrectly
83 ignored in the scan results, CJK terms in particular.
87 Fix bug in dictionary component of Zebra that could lead to
88 inconsistent register assert for large deleteions.
90 Improve estimate hits for phrase searches.
94 Add Debian package for Ubuntu maverick.
96 Update to newer Libxml2/Libxslt for Windows package.
98 Escape-sequences are disabled for RPN-queries with truncation=105/106.
99 These, unlike regular expressions, do not support \-sequences .
101 --- 2.0.44 2010/06/29
103 grs1: avoid term_len < 0 for .abs operator 'range'
105 ICU: fix use of un-init variable.
107 More reasonable approx hits for truncated searches.
109 Updates WRT Odr_int (YAZ 4).
111 --- 2.0.43 2009/11/05
113 Fix hits counts for searches when @attr 12=n is in use. This bug
114 was introduced in 2.0.40.
116 --- 2.0.42 2009/10/08
118 Proximity modifications. The optimized proximity now deals with more
119 cases, ie all prox of the form @prox 0 d 1 1,2,3 k 2 ..
120 That's exlusive==0, any distance, ordered (true), relation (<, =, <=),
123 Fix bug WRT inconsistent registers, bug #3062.
125 Fix install doc rule so it's compatible with Automake 1.11.
127 --- 2.0.41 2009/08/24
129 Fix typos and other errors in the documentation. Thanks to Galen
132 Fix DOM filter so that full record ID (z:id) if given is used verbatim
133 rather than truncated until first blank - in other words use memcpy
134 rather than sscanf. For PI fix record attributes parsing which was
137 --- 2.0.40 2009/07/13
139 Fixed problem in result set handling and segment handling.
141 --- 2.0.39 2009/07/09
143 Improved speed of record fetching by using a different block sizes
146 Added zlib-compression of recd-storage (record data). This is enabled
147 by using recordCompression: zlib in zebra.cfg.
149 Dictionary delete more agressive (dict_del_string).
151 --- 2.0.38 2009/06/19
153 Improved estimated hits for AND operation (bug #2907)
155 Fixed problem with register area growing after "drop DB". (bug #2913).
157 --- 2.0.37 2009/05/18
159 Example with marc21 is now installed and part of packages.
161 Fixed XSL for OAI example.
163 Fixed problem with generic proximity handling.
165 Added new ranking handler: rank-2. This is a combination of rank-1 and
166 static rank.. The staticrank is inverse (lowest value comes first, etc..).
167 rank-2 thus substracts that from score. This allows a system to specify
168 a "base" rank (=staticrank).
170 --- 2.0.36 2009/02/17
172 Added implementation-codes directive for .mar files.
174 Avoid error for missing recordId when zebraidx' option -s is in use.
176 Fixed problem with some disk blocks not beeing freed correctly when
177 'drop database' is used.
179 --- 2.0.34 2008/11/06
181 Facets can now be performed on sort registers (:s), not just regular indexes
182 (:w, :p) etc.. The performance appers to be much better than before.
184 Added a facility to embed metadata for records generated by the DOM XML
185 filter. The meta data step is triggered by a 'process-meta' section in the
186 retrieve section of the dom config, e.g.
187 <retrieve name="myelementset">
188 <xslt stylesheet="my-usual.xsl"/>
191 The meta section substitutes metadata for all elements called 'meta' in
192 namespace http://indexdata.com/zebra-2.0 . The meta element must have
193 exactly one attribute, name, which specifies the special
194 element set name which is equivalent to the suffix to zebra:: for
195 non-embedded special retrievals. This allows snippets, facets etc to be
198 Fixed bug #2202: incorrect sorting order when searching multiple databases.
200 --- 2.0.32 2008/06/06
204 --- 2.0.30 2008/05/14
206 Changed service name for Windows. Bug #978.
208 Fixed the alwaysmatches including _ALLRECORDS for ICU term indexing. Bug #2139.
210 --- 2.0.28 2008/04/03
212 Handle right-truncation for ICU normalized terms.
214 Updated OAI-PMH example.
216 --- 2.0.26 2008/01/28
218 Fixes for searches on Chinese text.
220 Fixes for scan using ICU indexing terms.
222 --- 2.0.24 2008/01/18
224 Fixed some memory violations for ICU enabled indexing that could be
225 triggered by long phrases.
227 Enable ICU on Windows. Thanks to Tumer Garip for makefile patches.
229 Fixed bug #2002: Zebra crashes during merge using ICU indexing.
231 --- 2.0.22 2007/12/20
233 Handle encoding errors for strings passed to ICU. (assert was
236 Added zebraidx command, adelete, which attempts to delete records.
237 It's like 'delete', but does not fail if a record does not exist.
239 --- 2.0.20 2007/12/19
241 Added experimental support for faceted results. This is implemented
242 as a special retrieval on a result set and is triggered using element
243 set name zebra::facet::f1:t1,f2,t2,.. which will return terms and
244 hit counts for field f1, type t1, field f2, type t2, .. The returned
245 data is packed as XML or SUTRS depending on record syntax.
247 Added support for Unicode-based indexing using ICU. This allows
248 locale specific scanning, sorting. The implementation is based on
249 the ICU utility part of YAZ 3.0.16 and later. See the manual as well
250 as the examples/marcxml for an example of the use of ICU.
252 --- 2.0.18 2007/09/19
254 Fixed bug with scan and staticrank enabled. Bug introduced in 2.0.16.
256 --- 2.0.16 2007/09/12
258 Scan now returns a displayTerm which closer to the original word/phrase
259 from original record.
261 Added snippet support. Element set name zebra::snippet will make
262 Zebra return an XML record with snippets (terms around matching terms).
264 Fixed bug #1142: Non-indexed but listed attributes issues diagnostic.
266 Fixed bug #1131: Missing value-of data in DOM filter.
268 Fixed bug #1049: zebra.cfg lines with leading space are ignored.
270 Fixed bug #1128: sortmax not honored.
272 Fixed bug #1121: Crash for some searches with customized string.chr.
274 --- 2.0.14 2007/05/09
276 Zebra uses the YAZ 3 API. Note that this changes the Zebra API
277 as well. The register layout is the same however.
279 Fixed bug #1114: scan within set may use excessive CPU.
281 Fixed memory leak that occurred in scan.
283 Fixed memory leak that occurred for each deleted record.
285 Optimize updates of records where content is almost identical to previous
286 version of record. This makes updating of the internal explain database
289 For RPN queries the index type (w,p,..) may be specified verbatim as
290 structure attribute with string value, e.g. @attr 4=w .
292 Changed record update API . It is now handled by function
293 zebra_record_update which does insert/replace/delete/update of records .
294 This function replaces zebra_record_{insert,delete} and
295 zebra_admin_exchange_record. The DOM filter uses this feature and the
296 @type attribute in record element specifies the action
297 insert/replace/delete/update.
299 Added support for multi-record updates (Bug #944). Based on patch from
302 --- 2.0.12 2007/03/07
304 Fixed bug with indexing of attributes for rec.grs-class of filters.
305 If X-Path was enabled xelm a/@b would be ignored.
307 Fixed bug in register system where 'no more space' messages was produced
308 even though there was plenty of space.
310 Fixed bug #884: Entity declarations in input are lost at retrieval time.
312 Implemented new filter 'dom'. See test/xslt/dom-config*xml for examples.
313 This, like alvis, performs indexing and retrieval using XSLT. But Unlike
314 alvis, it allows multiple XSLT steps to be performed and does ISO2709
317 --- 2.0.10 2007/01/24
319 Staticrank indexing is now an index register type defined in default.idx
320 via directive 'staticrank'. The 'staticrank' directive for grs is no longer
321 supported (was only implemented for Zebra 2.0.8).
323 For searches, allow truncmax value to be controlled with attribute 13.
324 If given, that overrides the value of 'truncmax'.
326 For truncations being limited (abort at truncmax terms), zebrasrv returns
327 SearchResponse with resultSetStatus=subset.
329 For estimated hit counts, zebrasrv returns SearchResponse with
330 resultSetStatus=estimate.
334 For searches, do not truncate more than at most 'truncmax' terms in one
335 single term with right-truncation/regular attribute. By default, 'truncmax',
338 Bug #781: Easier tracking of result sets. We only do this when mkstemp
339 is available (most moderun Unixes supports this). The PID is included
340 in filename : tempdir/zrs_PID_XXXXXX.
342 Added support for specification of staticrank for grs-class of filters.
343 This is enabled by using 'staticrank indexname' in .abs. Contents of
344 indexname (elm ... indexname:w) is then used as value for staticrank.
346 Implemented sorting via the ISAMB system. To enable, use sortindex:i in
349 Added special retrieval support for sort keys. These keys can also be
350 fetched using zebra::index:field:s
352 Added support for specification of approximative limits for whole query.
353 This is specified as attribute type 12. Semantics is the same as
354 estimatehits in zebra.cfg.
358 Fixed bug #736: Updates gets slower.
360 Fixed bug #735: Delete fails to process rest of file after a record that
363 Added RPM package for Zebra 2.
365 Improved indexing speed for large documents.
367 Added support for special utility retrieval zebra:: which offers retrieval
368 of fundamental properties for record, such as indexed terms, raw record,
369 and system record ID.
373 Fixed bug #47: Commit needs to check for roll-back.
375 Fixed bug #672: Trailing characters in password are ignored
377 Added extra presence check for tcl.h, because some systems have
378 tclConfig.sh installed even though Tcl C headers are missing.
380 Optimized melm performance.
382 Do not use sync(2) during commit (but rely on sync'd individual files).
384 Fixed bug in ISAMB's utility function decode_ptr. With gcc -O3 on some
385 platforms the src argument was not updated. Problem was compiler
386 optimization due to strict aliasing rules.
390 Bug fixes: #638, #647, #657, #669.
392 Implement skip of 0 hit counts in scan. Useful for scan operations
393 limited by a result set.
395 Honor position attribute, i.e. allow first-in-field search. To
396 enable this, "firstinfield 1" must be given for an index in
397 default.idx. Enabled in tab/default.idx for w. At this stage
398 first-in field is supported for phrase/and-list/or-list searches
400 Common stream reader interface for record filters (struct ZebraRecStream).
402 Debian package fix: packages idzebra-2.0 + libidzebra-2.0-modules did
403 not depend properly on sub packages.
407 New record filter (record type) 'alvis' which uses XSLT transformations
408 to drive both indexing as well as retrieval. See example configuration in the
409 'example/alvis-oai' directory.
411 'isamb' is now the default ISAM system. In Zebra 1.3, the default ISAM was
412 'isamc'. The type used can still be configured with the 'isam' setting
415 Index structure is now 64-bit based, also on 32 bit systems.
416 There are no more 2GB register file limits.
418 Extended search result tuning. Approximate limit for terms can be enabled
419 and specified with attribute 11. The (approx or exact) hit count is returned
420 as part of the search response as in 1.3 series. The subqueryID of a search
421 term hit count can be specified with attribute 10.
423 Zebra uses string attributes for indexing internally. Using set+numeric
424 use attribute can still be used. This is a search-only conversion which
425 inspects '*.att'-set files as indicated using attset-directives in 'zebra.cfg'.
426 'attset' references are no longer required, but when used they deserve
427 as "check" for that the index names used are also present in '*.att'.
429 Zebra record filters (record type handlers) may be built as loadable
430 modules (.so's) on Unix. In particular the Zebra 2.0 Debian package uses
431 separate packages for each of them. This also means that zebra programs
432 such as zebraidx is no longer depending on Tcl/other..
434 Documentation updates, especially on query structure and syntax, SRU,
435 XSLT support, alvis filter module, and many added examples.
437 Improved logging of the 'zebrasrv' and 'zebraidx' binaries.
439 Improved debian package structure.
441 --- 1.3.16 2004/08/16
