Michael McCandless commented on LUCENE-1410:
--------------------------------------------
Thanks for sharing these thorough results Renaud!
Curious that PFOR/FOR don't do well during searching... have you tried
profiling? Maybe something silly is going one.
One issue is MUST mixed with other clauses -- the scoring for such a query will
do alot of seeking, which for block based codecs will be costly. But it's
still strange you don't see speedups for single term query. Have you tried
only SHOULD clauses?
