             Summary: 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

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). I have no idea if this is the problem in SOLR-3636.
