all in RAM is completely different. all on disk will be bad, because when traversing terms in the FST, its random access all the way. MMAP changes nothing: as its not a sequential pattern.. and things like asking for a term range would be extra bad. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
