The +snippet_add_complete_fields (chr-system) now takes the indexing term +verbatim and makes that the display term. + +--- 2.0.48 2011/06/28 + +Utility idebra-abs2dom part of distribution and deb+RPM packages. + +Fix problem with scan and complete subfields (:p) . In some cases, +the display scan terms, would be invalid. + +--- 2.0.47 2011/05/24 + +RPM: Store libraries in /usr/lib64 on 64-bit platforms. + +Zebra honors SRU sortkeys. If used with YAZ 4.2.0 or later, +CQL sortby is honored as well. + +Fix scan's handling of normalized terms. Some terms were incorrectly +ignored in the scan results, CJK terms in particular. + +--- 2.0.46 2011/03/23 + +Fix bug in dictionary component of Zebra that could lead to +inconsistent register assert for large deleteions. + +Improve estimate hits for phrase searches. + +--- 2.0.45 2010/12/22 + +Add Debian package for Ubuntu maverick. + +Update to newer Libxml2/Libxslt for Windows package. + +Escape-sequences are disabled for RPN-queries with truncation=105/106. +These, unlike regular expressions, do not support \-sequences . + +--- 2.0.44 2010/06/29 + +grs1: avoid term_len < 0 for .abs operator 'range' + +ICU: fix use of un-init variable. + +More reasonable approx hits for truncated searches. + +Updates WRT Odr_int (YAZ 4). + +--- 2.0.43 2009/11/05 + +Fix hits counts for searches when @attr 12=n is in use. This bug +was introduced in 2.0.40. + +--- 2.0.42 2009/10/08 + +Proximity modifications. The optimized proximity now deals with more +cases, ie all prox of the form @prox 0 d 1 1,2,3 k 2 .. +That's exlusive==0, any distance, ordered (true), relation (<, =, <=), +known unit word. + +Fix bug WRT inconsistent registers, bug #3062. + +Fix install doc rule so it's compatible with Automake 1.11. + +--- 2.0.41 2009/08/24 + +Fix typos and other errors in the documentation. Thanks to Galen +Charlton. + +Fix DOM filter so that full record ID (z:id) if given is used verbatim +rather than truncated until first blank - in other words use memcpy +rather than sscanf. For PI fix record attributes parsing which was +completely broken. + +--- 2.0.40 2009/07/13 + +Fixed problem in result set handling and segment handling. + +--- 2.0.39 2009/07/09 + +Improved speed of record fetching by using a different block sizes +for recd{A,B}. + +Added zlib-compression of recd-storage (record data). This is enabled +by using recordCompression: zlib in zebra.cfg. + +Dictionary delete more agressive (dict_del_string). + +--- 2.0.38 2009/06/19 + +Improved estimated hits for AND operation (bug #2907) + +Fixed problem with register area growing after "drop DB". (bug #2913). + +--- 2.0.37 2009/05/18 + +Example with marc21 is now installed and part of packages. + +Fixed XSL for OAI example. + +Fixed problem with generic proximity handling. + +Added new ranking handler: rank-2. This is a combination of rank-1 and +static rank.. The staticrank is inverse (lowest value comes first, etc..). +rank-2 thus substracts that from score. This allows a system to specify +a "base" rank (=staticrank). + +--- 2.0.36 2009/02/17 + +Added implementation-codes directive for .mar files. + +Avoid error for missing recordId when zebraidx' option -s is in use. + +Fixed problem with some disk blocks not beeing freed correctly when +'drop database' is used. + +--- 2.0.34 2008/11/06 + +Facets can now be performed on sort registers (:s), not just regular indexes +(:w, :p) etc.. The performance appers to be much better than before. + +Added a facility to embed metadata for records generated by the DOM XML +filter. The meta data step is triggered by a 'process-meta' section in the +retrieve section of the dom config, e.g. + + + + +The meta section substitutes metadata for all elements called 'meta' in +namespace http://indexdata.com/zebra-2.0 . The meta element must have +exactly one attribute, name, which specifies the special +element set name which is equivalent to the suffix to zebra:: for +non-embedded special retrievals. This allows snippets, facets etc to be +included. + +Fixed bug #2202: incorrect sorting order when searching multiple databases. + +--- 2.0.32 2008/06/06 + +Fixed OAI example. + +--- 2.0.30 2008/05/14 + +Changed service name for Windows. Bug #978. + +Fixed the alwaysmatches including _ALLRECORDS for ICU term indexing. Bug #2139. + +--- 2.0.28 2008/04/03 + +Handle right-truncation for ICU normalized terms. + +Updated OAI-PMH example. + +--- 2.0.26 2008/01/28 + +Fixes for searches on Chinese text. + +Fixes for scan using ICU indexing terms. + +--- 2.0.24 2008/01/18 + +Fixed some memory violations for ICU enabled indexing that could be +triggered by long phrases. + +Enable ICU on Windows. Thanks to Tumer Garip for makefile patches. + +Fixed bug #2002: Zebra crashes during merge using ICU indexing. + +--- 2.0.22 2007/12/20 + +Handle encoding errors for strings passed to ICU. (assert was +thrown earlier). + +Added zebraidx command, adelete, which attempts to delete records. +It's like 'delete', but does not fail if a record does not exist. + +--- 2.0.20 2007/12/19 + +Added experimental support for faceted results. This is implemented +as a special retrieval on a result set and is triggered using element +set name zebra::facet::f1:t1,f2,t2,.. which will return terms and +hit counts for field f1, type t1, field f2, type t2, .. The returned +data is packed as XML or SUTRS depending on record syntax. + +Added support for Unicode-based indexing using ICU. This allows +locale specific scanning, sorting. The implementation is based on +the ICU utility part of YAZ 3.0.16 and later. See the manual as well +as the examples/marcxml for an example of the use of ICU. + +--- 2.0.18 2007/09/19 + +Fixed bug with scan and staticrank enabled. Bug introduced in 2.0.16. + +--- 2.0.16 2007/09/12 + +Scan now returns a displayTerm which closer to the original word/phrase +from original record. + +Added snippet support. Element set name zebra::snippet will make +Zebra return an XML record with snippets (terms around matching terms). + +Fixed bug #1142: Non-indexed but listed attributes issues diagnostic. + +Fixed bug #1131: Missing value-of data in DOM filter. + +Fixed bug #1049: zebra.cfg lines with leading space are ignored. + +Fixed bug #1128: sortmax not honored. + +Fixed bug #1121: Crash for some searches with customized string.chr. + +--- 2.0.14 2007/05/09 + +Zebra uses the YAZ 3 API. Note that this changes the Zebra API +as well. The register layout is the same however. + +Fixed bug #1114: scan within set may use excessive CPU. + +Fixed memory leak that occurred in scan. + +Fixed memory leak that occurred for each deleted record. + +Optimize updates of records where content is almost identical to previous +version of record. This makes updating of the internal explain database +faster too. + +For RPN queries the index type (w,p,..) may be specified verbatim as +structure attribute with string value, e.g. @attr 4=w . + +Changed record update API . It is now handled by function +zebra_record_update which does insert/replace/delete/update of records . +This function replaces zebra_record_{insert,delete} and +zebra_admin_exchange_record. The DOM filter uses this feature and the +@type attribute in record element specifies the action +insert/replace/delete/update. + +Added support for multi-record updates (Bug #944). Based on patch from +Hans-Werner Hilse. + +--- 2.0.12 2007/03/07 + +Fixed bug with indexing of attributes for rec.grs-class of filters. +If X-Path was enabled xelm a/@b would be ignored. + +Fixed bug in register system where 'no more space' messages was produced +even though there was plenty of space. + +Fixed bug #884: Entity declarations in input are lost at retrieval time. + +Implemented new filter 'dom'. See test/xslt/dom-config*xml for examples. +This, like alvis, performs indexing and retrieval using XSLT. But Unlike +alvis, it allows multiple XSLT steps to be performed and does ISO2709 +reading. Bug #843. + +--- 2.0.10 2007/01/24 + +Staticrank indexing is now an index register type defined in default.idx +via directive 'staticrank'. The 'staticrank' directive for grs is no longer +supported (was only implemented for Zebra 2.0.8). + +For searches, allow truncmax value to be controlled with attribute 13. +If given, that overrides the value of 'truncmax'. + +For truncations being limited (abort at truncmax terms), zebrasrv returns +SearchResponse with resultSetStatus=subset. + +For estimated hit counts, zebrasrv returns SearchResponse with +resultSetStatus=estimate. + +--- 2.0.8 2007/01/15 + +For searches, do not truncate more than at most 'truncmax' terms in one +single term with right-truncation/regular attribute. By default, 'truncmax', +is 10000. + +Bug #781: Easier tracking of result sets. We only do this when mkstemp +is available (most moderun Unixes supports this). The PID is included +in filename : tempdir/zrs_PID_XXXXXX. + +Added support for specification of staticrank for grs-class of filters. +This is enabled by using 'staticrank indexname' in .abs. Contents of +indexname (elm ... indexname:w) is then used as value for staticrank. + +Implemented sorting via the ISAMB system. To enable, use sortindex:i in +zebra.cfg. + +Added special retrieval support for sort keys. These keys can also be +fetched using zebra::index:field:s + +Added support for specification of approximative limits for whole query. +This is specified as attribute type 12. Semantics is the same as +estimatehits in zebra.cfg. + +--- 2.0.6 2006/11/28 + +Fixed bug #736: Updates gets slower. + +Fixed bug #735: Delete fails to process rest of file after a record that +does not exist, + +Added RPM package for Zebra 2. + +Improved indexing speed for large documents. + +Added support for special utility retrieval zebra:: which offers retrieval +of fundamental properties for record, such as indexed terms, raw record, +and system record ID. + +--- 2.0.4 2006/10/16 + +Fixed bug #47: Commit needs to check for roll-back. + +Fixed bug #672: Trailing characters in password are ignored + +Added extra presence check for tcl.h, because some systems have +tclConfig.sh installed even though Tcl C headers are missing. + +Optimized melm performance. + +Do not use sync(2) during commit (but rely on sync'd individual files). + +Fixed bug in ISAMB's utility function decode_ptr. With gcc -O3 on some +platforms the src argument was not updated. Problem was compiler +optimization due to strict aliasing rules. + +--- 2.0.2 2006/09/22 + Bug fixes: #638, #647, #657, #669. Implement skip of 0 hit counts in scan. Useful for scan operations
