Hi All: A new binary distribution of Lucene Domain Index (2.9.0.1.0) for Oracle 10g/11g has been released. Lucene Domain Index is integration of Lucene Project running inside the Oracle JVM and integrated to the SQL layer by adding a new index type. This new version uses latest Lucene 2.9.0 core libraries and introduces some of the changes on API. Here complete list of changes: * Tested with Oracle 11gR2, 11gR1 and 10.2 databases. * DefaultUserDataStore do a SAX parsing to get text nodes and attributes from an XMLType value. * A SimpleLRUCache is used to load rowids and his associated Lucene doc id, this reduce memory consumption when querying very big tables. A new parameter has been added, CachedRowIdSize by default 10000 to control the size of the LRU cache. * Lucene Domain Index core was updated to use TopFieldCollector and to avoid computation time when lscore() is not used. * Two new parameter has been added NormalizeScore which control when to track the Max Score and PreserveDocIdOrder when querying, both parameters are consequence of new Lucene Collector API and boost the performance when querying. * A table alias L$MT is defined for the master table associated to the index to be used in complex queries associating columns from master tables and columns from dependant tables.
