From the .abs-file the +"tagset" directive takes a third optional integer type for the tag set +referenced. From a .tag-file the "include" directive takes a third +optional type as well. The old "type" directive in the tag set itself +is still recognized but acts as the default type for the tag set. + +Zebra supports the specification of arbitrary attributes sets, schemas +and tag sets, because of the change in YAZ' OID management system. + +Fixed bug in Sort that caused it NOT to use character mapping as it +should. Zebra now uses GNU configure to generate Makefile(s). Added un-optimised support for left and left/right truncation attributes. -Added support for relational operators on text when using -RPN queries. +Added support for relational operators on text when using RPN queries. -Added support for sort specifications in RPN queries. Type 7 -specifies 'sort' where value 1=ascending, value 2=descending. -The use attribute specifies the field criteria as usual. -The term specifies priority (0=first, 1=second). +Added support for sort specifications in RPN queries.

Changed the way use attributes are specified in the recordId specification. Maximum number of databases in one Zebra register increased. -New setting, databasePath, which specifies that first directory -during update traversal is the database name (instead of -a fixed one). +New setting, databasePath, which specifies that first directory during +update traversal is the database name (instead of a fixed one). -New setting, explainDatabase, which specifies that databases -are EXPLAIN aware. +New setting, explainDatabase, which specifies that databases are +EXPLAIN aware. Modified Zebra so that it works with ASN.1 compiled code for YAZ. Implemented EXPLAIN database maintenance. Zebra automatically generate - and update CategoryList, TargetInfo, DatabaseInfo, -AttributeSetInfo and AttributeDetails records at this stage. -The records may be transferred as GRS-1, SUTRS or Explain. +AttributeSetInfo and AttributeDetails records at this stage. The +records may be transferred as GRS-1, SUTRS or Explain. Fixed register spec so that colon isn't treated as size separator unless followed by [0-9+-] in order to allow DOS drive specifications. Fixed two bugs in ISAMC system. -Changed the way Zebra keeps its maintenance information. Records -in "SGML" notation using an EXPLAIN schema is now used when -appropriate. +Changed the way Zebra keeps its maintenance information about attribute +sets, available attributes, etc.. Records in "SGML" notation using an +EXPLAIN schema is now used when appropriate. -Bug fix: Index didn't handle update/insert/delete of the same -record (i.e. same recordId) in one run (one invocation of zebraidx). -Only the first occurence of a record is considered. +Bug fix: Index didn't handle update/insert/delete of the same record +(i.e. same recordId) in one run (one invocation of zebraidx). Only the +first occurence of a record is considered. Most searches now return correct number of hits. New modular ranking system. Interested programmers are encouraged to inspect rank1.c and improve the algorithm. -Bug fix: Lock files weren't removed as they should when using NT. +Bug fix: Lock files weren't removed as they should on NT. Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to -specify a "sort register".
