Luceneutil doesnt yet benchmark more complicated BQs (e.g. nested ones, or
minShouldMatch, or whatever).
So we don't see any benefit in these benchmarks.
> clean up booleanquery conjunction optimizations a bit

> Key: LUCENE-4236
> URL: https://issues.apache.org/jira/browse/LUCENE-4236
> Project: Lucene - Java
> Issue Type: Improvement
> Reporter: Robert Muir
> Fix For: 4.0, 5.0
>
> Attachments: LUCENE-4236.patch, LUCENE-4236.patch, LUCENE-4236.patch
>
>
> After LUCENE-3505, I want to do a slight cleanup:
> * compute the term conjunctions optimization in scorer(), so its applied even
> if we have optional and prohibited clauses that dont exist in the segment
> (e.g. return null)
> * use the term conjunctions optimization when optional.size() ==
> minShouldMatch, as that means they are all mandatory, too.
> * don't return booleanscorer1 when optional.size() == minShouldMatch, because
> it means we have required clauses and in general BS2 should do a much better
> job (e.g. use advance).
