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