Package org.sigpath.fulltext Description

Classes that support fast queries in full text. Three strategies are supported by SigPath. Each strategy is implemented in an implementation of FullTextSearchManager:

  • JdoFullTextSearchManager: Java Data Object implementation of an inverted index. Without compression this uses a fair amount of storage space for the index, but is fast.
  • LuceneFullTextSearchManager: Lucene full text index. Lucene is the Jakarta implementation of a compressed inverted file index. The index is compressed and stored on disk separately from the database.
  • OracleFullTextSearchManager: Oracle text indexing. This requires a separate oracle database to store the index. We used it for a while but dropped the option because of the management cost of maintaining another database. The implementation has not been tested in some time.
