1 Zebra now uses GNU configure to generate Makefile(s).
3 Added un-optimised support for left and left/right truncation attributes.
5 Added support for relational operators on text when using
8 Added support for sort specifications in RPN queries. Type 7
9 specifies 'sort' where value 1=ascending, value 2=descending.
10 The use attribute specifies the field criteria as usual.
11 The term specifies priority (0=first, 1=second).
13 Changed the way use attributes are specified in the recordId
16 Maximum number of databases in one Zebra register increased.
18 New setting, databasePath, which specifies that first directory
19 during update traversal is the database name (instead of
22 New setting, explainDatabase, which specifies that databases
25 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
27 Implemented EXPLAIN database maintenance. Zebra automatically
28 generate - and update CategoryList, TargetInfo, DatabaseInfo,
29 AttributeSetInfo and AttributeDetails records at this stage.
30 The records may be transferred as GRS-1, SUTRS or Explain.
32 Fixed register spec so that colon isn't treated as size separator
33 unless followed by [0-9+-] in order to allow DOS drive specifications.
35 Fixed two bugs in ISAMC system.
37 Changed the way Zebra keeps its maintenance information. Records
38 in "SGML" notation using an EXPLAIN schema is now used when
41 Bug fix: Index didn't handle update/insert/delete of the same
42 record (i.e. same recordId) in one run (one invocation of zebraidx).
43 Only the first occurence of a record is considered.
45 Most searches now return correct number of hits.
47 New modular ranking system. Interested programmers are encouraged to
48 inspect rank1.c and improve the algorithm.
50 Bug fix: Lock files weren't removed as they should when using NT.
52 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
53 specify a "sort register". Refer to the gils sample records which
54 refer to index type "s" which is specified as "sort" in the default.idx
55 file. Each sort criteria can either be Ascending or Descending and
56 at most three sort elements can be specified.
58 Bug fix: Character mapping didn't work for text files.
62 Simple ranked searches now return correct number of hits.
64 The test option (-s) only makes a read-lock on the index as well
65 as using read-only operations anywhere.
67 Moved towards generic character mapping. Configuration file default.idx
68 specifies character map files for register types w, p, u, etc.
70 Implemented "begin variant" for the sgml.regx - filter.
72 Fixed a few memory leaks.
74 Added support for C++, headers uses extern "C" for public definitions.
76 Bug fix: The show records facility (-s) only displayed information for
77 the first record in a file (and not for every record in the file).
79 Added option "-f <n>" to limit the logging of record operations. After
80 <n> records has been processed no logging is performed (unless errors
83 Bug fix: the compressed ISAM system didn't handle update operations
86 Added setting, "maxResultSetSize", to hold the number of records to
89 Bug fix: Complete phrase did't work for search operations.
91 Bug fix: temporary result sets weren't deleted.
93 Reduced disk space for saved keys (storeKeys = 1).
95 Added optional, physical ANY (key replication)
97 Implemented proximity operator in search.
99 Bug fix: the path name buffers used by file match traversal routines
100 have been extended to support long file names.
102 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
103 configuration file. The resulting register without "storeKeys" is about
104 half the size, and the memory used by zebraidx during phase 2 (merge) is
105 reduced to a minimum.
107 Reworked the way Regexp-2 queries with error tolerance are handled and
108 specified. The documentation has been updated accordingly.
110 Bug fix: Zebrasrv didn't search correctly when queries contained masking
111 characters. This bug was introduced in 1.0a8.
113 Zebrasrv now tag records with the proper database name.
115 New settings, memMax and keyTmpDir.
117 Changed name of setting lockDir (previously called lockPath) and
118 setTmpDir (previously called tempSetPath).
120 Generalized and changed record type specifications. In short, there are:
122 grs.sgml structured, "SGML-like" syntax
123 grs.regx.<filter> structured, Regular expression filter
124 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
125 is the name of an abstract syntax file.
126 Bug fix: Result sets weren't sorted in operations involving boolean
127 operations with "ranked" operands.
131 Added national character-handling subsystem.
135 Small modifications to input filters and profiles.
137 Added support for SOIF syntax (with private OID).
141 Fixed buffer-size problem in indexing.
143 Added compression to temporary files for updating.
145 Added phrase registers.
147 Added dynamic mapping of search attribute to multiple termlists (ANY).
149 Scan support in multiple databases/registers.
151 Configuration settings are case-insensitive and single dash (-)
152 characters are ignored in comparisons.
154 The index processing ignores empty files - warning given.
156 New option to zebraidx (-V) displays version information.
160 Fixed problem in file-update system.
162 Fixed problem in shadow system; register was sometimes corrupted after
167 Fixed problems in the ISAM subsystem. Caused difficulties when updating
170 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
171 the rank and record number.
173 Fixed bug in the isam subsystem - caused a malfunction when accessing
174 words which occurred more than 10000 times.
176 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
179 Server can now run under inetd. Use option -i, and -w <directory> to
180 set working directory to desired location.
182 New zebraidx command: clean - removes temporary shadow files.
184 Fixed bug in ISAM system. Occurred rarely during register updates.
186 Logging during index merge phase is improved. The remaining running
189 Temporary files generated by zebraidx are removed after each run.
191 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
192 when doing scan operations in dictionaries with European characters.
196 A whole slew of updates, to make the first publicized release. Get the doc
201 Memory-problems in ISAM fixed. More blocktypes added to the default setup
202 to increase performance on larger databases.
204 Various minor changes in data management system.
208 A couple of portability-problems resolved.
210 Changed some malloc() to xmalloc().
