What happens to the document numbers when documents are deleted and the segment merged? Is the document number of all the documents reset to be sequential based on some offset for each segment? Is there any pattern that might be followed instead of recreating the entire array. I know this prob

Hi again :) Hits versus HitCollector I implemented HitCollector, but it didn't seem much faster. I'm guessing its because Hits doesn't seem to run all the way through the resultset before finishing whereas HitsCollector does ? So, What I'd really like to know, is, does a Hits combined

Hi, I was wondering why reader.document(i) is relatively slow ? Given that it is, perhaps could anyone tell me if this would be work? I'm currently trying to create a fast lookup, and the reader.doc(i) is quite slow. Question -- could I create this an array in the insertion order at In

This is not easy to do efficiently. The efficiency of the search code depends on not constructing Document objects for every match. Thus it is hard to efficiently perform calculations which require field values. Things are easy if you need date order, and you have added documents in date order.
