Question: Can lucene do parallel indexing?

If I'm using a computer that has multiple cores, or if I want to use several computers to speed up the indexing process, how should I do that? Is there some kind of support for that in the API? David Lee

Nested Proximity searches

Is it possible to do nested proximity searches with lucene? i.e. can I say I want a to be within 1 word of b and then that group to be within 4 words of c? The syntax ""a b"~1" c"~4 doesn't seem to work (since it treats the first two quotes as a pair and the later 2 as another pair).

Do Lucene Deletes delete the physical file? If yes, is there a way not to?

Lucene Index Structure

Clarification question: If I don't store term vectors, then I: -- won't have information on the position of matching terms -- I don't have the term frequency vector -- but I should still have the frequency of terms per document in the .frq file, right? So what's the difference between the term f

Lucene AND queries

Hi, I was wondering when lucene queries two or more terms, does that mean the time it takes will be twice as long? For example if I search +lucene +apache, then does lucene get all the documents that match 'lucene' and all the documents that match 'apache', and then combine them together? Or can it
