Subject Re: Combining scores
Date Tue, 21 Nov 2006 13:36:38 GMT
This is a *really* simplistic approach, but why not just submit all 4 or 5
queries at once ina BooleanQuery and let Lucene do all the work for you? Or
are the 4 or 5 queries such that they don't combine easily with MUST,
MUST_NOT or SHOULD in a BooleanQuery?
