Hi Daniel, I couldn't figure out how to use the PharsePrefixQuery with a phase like "java* developer". It only provides method to add terms. Can a term contain wildcard character in lucene? Thanks, Terence > On Wednesday 24 November 2004 08:16, Morus Walter wrote: > > > Lucene itself doesn't

RE: Re: Re: OutOfMemoryError

Hi David, In my test program, I invoke the IndexSearcher.close() method at the end of the loop. However, it doesn't seems to release the memory. My concern is that even though I put the IndexSearcher.close() statement in the hook methods, it may not release all the memory until the application
