Re: Poor performance "race condition" in FieldSortedHitQueue

Hi, Sometimes when the user does a search on the same term at the same time, there is a delay in the search and the memory used considerably goes high. I was going through the lucene user list and saw this discussion about race condition. http://www.gossamer-threads.com/lists/lucene

"Catalog" backend for document stored fields?

Hello to all of you! I'm using Lucene to index millions a relatively small documents. In fact, I'm indexing logs from a transaction-based application. Each document represents what happened inside during 'transaction'. Each of them is composed by 5-6 main 'states' which are themselves compos

RE: Wildcard Search and "Note: You cannot use a * or ? symbol as the first character of a search"

Don't know Lucene internals, but I'd say you'd have to create your own 'reverse' B-Tree of some kind (Lucene gurus will probably advise you on the place where this can be changed in the Lucene). Even if this functionality can't be redefined in Lucene itself, you can easily implement it by yourself
