1 For RPN queries the index type (w,p,..) may be specified verbatim as
2 structure attribute with string value, e.g. @attr 4=w .
4 Changed record update API . It is now handled by function
5 zebra_record_update which does insert/replace/delete/update of records .
6 This function replaces zebra_record_{insert,delete} and
7 zebra_admin_exchange_record. The DOM filter uses this feature and the
8 @type attribute in record element specifies the action
9 insert/replace/delete/update.
11 Added support for multi-record updates (Bug #944). Based on patch from
16 Fixed bug with indexing of attributes for rec.grs-class of filters.
17 If X-Path was enabled xelm a/@b would be ignored.
19 Fixed bug in register system where 'no more space' messages was produced
20 even though there was plenty of space.
22 Fixed bug #884: Entity declarations in input are lost at retrieval time.
24 Implemented new filter 'dom'. See test/xslt/dom-config*xml for examples.
25 This, like alvis, performs indexing and retrieval using XSLT. But Unlike
26 alvis, it allows multiple XSLT steps to be performed and does ISO2709
31 Staticrank indexing is now an index register type defined in default.idx
32 via directive 'staticrank'. The 'staticrank' directive for grs is no longer
33 supported (was only implemented for Zebra 2.0.8).
35 For searches, allow truncmax value to be controlled with attribute 13.
36 If given, that overrides the value of 'truncmax'.
38 For truncations being limited (abort at truncmax terms), zebrasrv returns
39 SearchResponse with resultSetStatus=subset.
41 For estimated hit counts, zebrasrv returns SearchResponse with
42 resultSetStatus=estimate.
46 For searches, do not truncate more than at most 'truncmax' terms in one
47 single term with right-truncation/regular attribute. By default, 'truncmax',
50 Bug #781: Easier tracking of result sets. We only do this when mkstemp
51 is available (most moderun Unixes supports this). The PID is included
52 in filename : tempdir/zrs_PID_XXXXXX.
54 Added support for specification of staticrank for grs-class of filters.
55 This is enabled by using 'staticrank indexname' in .abs. Contents of
56 indexname (elm ... indexname:w) is then used as value for staticrank.
58 Implemented sorting via the ISAMB system. To enable, use sortindex:i in
61 Added special retrieval support for sort keys. These keys can also be
62 fetched using zebra::index:field:s
64 Added support for specification of approximative limits for whole query.
65 This is specified as attribute type 12. Semantics is the same as
66 estimatehits in zebra.cfg.
70 Fixed bug #736: Updates gets slower.
72 Fixed bug #735: Delete fails to process rest of file after a record that
75 Added RPM package for Zebra 2.
77 Improved indexing speed for large documents.
79 Added support for special utility retrieval zebra:: which offers retrieval
80 of fundamental properties for record, such as indexed terms, raw record,
85 Fixed bug #47: Commit needs to check for roll-back.
87 Fixed bug #672: Trailing characters in password are ignored
89 Added extra presence check for tcl.h, because some systems have
90 tclConfig.sh installed even though Tcl C headers are missing.
92 Optimized melm performance.
94 Do not use sync(2) during commit (but rely on sync'd individual files).
96 Fixed bug in ISAMB's utility function decode_ptr. With gcc -O3 on some
97 platforms the src argument was not updated. Problem was compiler
98 optimization due to strict aliasing rules.
102 Bug fixes: #638, #647, #657, #669.
104 Implement skip of 0 hit counts in scan. Useful for scan operations
105 limited by a result set.
107 Honor position attribute, i.e. allow first-in-field search. To
108 enable this, "firstinfield 1" must be given for an index in
109 default.idx. Enabled in tab/default.idx for w. At this stage
110 first-in field is supported for phrase/and-list/or-list searches
112 Common stream reader interface for record filters (struct ZebraRecStream).
114 Debian package fix: packages idzebra-2.0 + libidzebra-2.0-modules did
115 not depend properly on sub packages.
119 New record filter (record type) 'alvis' which uses XSLT transformations
120 to drive both indexing as well as retrieval. See example configuration in the
121 'example/alvis-oai' directory.
123 'isamb' is now the default ISAM system. In Zebra 1.3, the default ISAM was
124 'isamc'. The type used can still be configured with the 'isam' setting
127 Index structure is now 64-bit based, also on 32 bit systems.
128 There are no more 2GB register file limits.
130 Extended search result tuning. Approximate limit for terms can be enabled
131 and specified with attribute 11. The (approx or exact) hit count is returned
132 as part of the search response as in 1.3 series. The subqueryID of a search
133 term hit count can be specified with attribute 10.
135 Zebra uses string attributes for indexing internally. Using set+numeric
136 use attribute can still be used. This is a search-only conversion which
137 inspects '*.att'-set files as indicated using attset-directives in 'zebra.cfg'.
138 'attset' references are no longer required, but when used they deserve
139 as "check" for that the index names used are also present in '*.att'.
141 Zebra record filters (record type handlers) may be built as loadable
142 modules (.so's) on Unix. In particular the Zebra 2.0 Debian package uses
143 separate packages for each of them. This also means that zebra programs
144 such as zebraidx is no longer depending on Tcl/other..
146 Documentation updates, especially on query structure and syntax, SRU,
147 XSLT support, alvis filter module, and many added examples.
149 Improved logging of the 'zebrasrv' and 'zebraidx' binaries.
151 Improved debian package structure.
