Consumes some 2x the memory of a RAMDirectory (in a term satured index) but is between 3x-60x faster depending on application and how one counts. Average query is about 8x faster. IndexWriter and IndexModifier have been realized in InterfaceIndexWriter and InterfaceIndexModifier. > InstantiatedIndex is wrapped in a new top layer index facade (class Index) that comes with factory methods for writers, readers and searchers for unison index handeling. There are decorators with notification handling that can be used for automatically syncronizing searchers on updates, et.c. > Index also comes with FS/RAMDirectory implementation. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscribe@lucene.apache.org For additional commands, e-mail: java-dev-help@lucene.apache.org
