By splitting up a large index into smaller indicies, you are linearizing the search time. Furthermore, that allows you to make your search distributable. -John On Wed, 21 Jul 2004 13:00:28 +1000, Anson Lau wrote: > Hello guys, > > What are some general techniques to make lucene search faster? > > I'm thinking about splitting up the index.
