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.
