Just a short one, it rocks in some cases (when actual BitSet/IntSet is compressable, long runs of set or clear bits...). Very good general BitSet representation
I have tried it and found no bugs so far (+- 2 months of using it) Unfortunately, there is an issue with Licence (not ASF compatible :( cheers PS: To use something like that with Lucene you will hit the problem with Filter interface that suports only BitSet. It means you will have to wait a bit until more flexible Filter interface gets accepted by the comunity. Apart from that, I would not evaluate too much, just take Lucene, it is briliant ;) PS1: If you are interested in compressed bit sets, try to search for "utilities for compact sparse filters lucene" --- Dupriez Christophe <[EMAIL PROTECTED]> wrote: > I am about to evaluate Lucene for replacing > current IR system of Belgian Poison Center. > > We are used to manage query refinements by > combining different searches with boolean > operators: we thus have to store the results > (or otherwise to remake them).
