1 Bug fix: Lock files weren't removed as they should when using NT.
3 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
4 specify a "sort register". Refer to the gils sample records which
5 refer to index type "s" which is specified as "sort" in the default.idx
6 file. Each sort criteria can either be Ascending or Descending and
7 at most three sort elements can be specified.
9 Bug fix: Character mapping didn't work for text files.
13 Simple ranked searches now return correct number of hits.
15 The test option (-s) only makes a read-lock on the index as well
16 as using read-only operations anywhere.
18 Moved towards generic character mapping. Configuration file default.idx
19 specifies character map files for register types w, p, u, etc.
21 Implemented "begin variant" for the sgml.regx - filter.
23 Fixed a few memory leaks.
25 Added support for C++, headers uses extern "C" for public definitions.
27 Bug fix: The show records facility (-s) only displayed information for
28 the first record in a file (and not for every record in the file).
30 Added option "-f <n>" to limit the logging of record operations. After
31 <n> records has been processed no logging is performed (unless errors
34 Bug fix: the compressed ISAM system didn't handle update operations
37 Added setting, "maxResultSetSize", to hold the number of records to
40 Bug fix: Complete phrase did't work for search operations.
42 Bug fix: temporary result sets weren't deleted.
44 Reduced disk space for saved keys (storeKeys = 1).
46 Added optional, physical ANY (key replication)
48 Implemented proximity operator in search.
50 Bug fix: the path name buffers used by file match traversal routines
51 have been extended to support long file names.
53 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
54 configuration file. The resulting register without "storeKeys" is about
55 half the size, and the memory used by zebraidx during phase 2 (merge) is
58 Reworked the way Regexp-2 queries with error tolerance are handled and
59 specified. The documentation has been updated accordingly.
61 Bug fix: Zebrasrv didn't search correctly when queries contained masking
62 characters. This bug was introduced in 1.0a8.
64 Zebrasrv now tag records with the proper database name.
66 New settings, memMax and keyTmpDir.
68 Changed name of setting lockDir (previously called lockPath) and
69 setTmpDir (previously called tempSetPath).
71 Generalized and changed record type specifications. In short, there are:
73 grs.sgml structured, "SGML-like" syntax
74 grs.regx.<filter> structured, Regular expression filter
75 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
76 is the name of an abstract syntax file.
77 Bug fix: Result sets weren't sorted in operations involving boolean
78 operations with "ranked" operands.
82 Added national character-handling subsystem.
86 Small modifications to input filters and profiles.
88 Added support for SOIF syntax (with private OID).
92 Fixed buffer-size problem in indexing.
94 Added compression to temporary files for updating.
96 Added phrase registers.
98 Added dynamic mapping of search attribute to multiple termlists (ANY).
100 Scan support in multiple databases/registers.
102 Configuration settings are case-insensitive and single dash (-)
103 characters are ignored in comparisons.
105 The index processing ignores empty files - warning given.
107 New option to zebraidx (-V) displays version information.
111 Fixed problem in file-update system.
113 Fixed problem in shadow system; register was sometimes corrupted after
118 Fixed problems in the ISAM subsystem. Caused difficulties when updating
121 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
122 the rank and record number.
124 Fixed bug in the isam subsystem - caused a malfunction when accessing
125 words which occurred more than 10000 times.
127 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
130 Server can now run under inetd. Use option -i, and -w <directory> to
131 set working directory to desired location.
133 New zebraidx command: clean - removes temporary shadow files.
135 Fixed bug in ISAM system. Occurred rarely during register updates.
137 Logging during index merge phase is improved. The remaining running
140 Temporary files generated by zebraidx are removed after each run.
142 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
143 when doing scan operations in dictionaries with European characters.
147 A whole slew of updates, to make the first publicized release. Get the doc
152 Memory-problems in ISAM fixed. More blocktypes added to the default setup
153 to increase performance on larger databases.
155 Various minor changes in data management system.
159 A couple of portability-problems resolved.
161 Changed some malloc() to xmalloc().
