Isn't that the same as using a boost 1, e.g. 0.1? That should be possible. no. a^-1 OR b A boost of -1 means that the score gets smaller if a document contains a with that boost appears. So it's somehow similar to NOT a, though less strict. A boost of 0.1 means that the score is increased less for an occurance of a. Usually one just want's the latter, but it's not the same. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Performance when computing computing a filter using hundreds of diff terms.
I'm trying to compute a filter to match documents in our index by a set of terms. For example some documents have a given field 'category' so I need to compute a filter with mulitple categories. The problem is that our category list is 200 items so it takes about 80 seconds to compute. We cache it of course but this seems WAY too slow. Is there anything I could do to speed it up? Maybe run the queries myself and then combine the bitsets? We're using a BooleanQuery with nested TermQueries to build up the filter...
