BlockJoinQuery doesn't implement boost
--------------------------------------
Key: LUCENE-3495
URL: https://issues.apache.org/jira/browse/LUCENE-3495
Project: Lucene - Java
Issue Type: Bug
Affects Versions: 3.4
Reporter: Robert Muir
Fix For: 3.5, 4.0
After reviewing LUCENE-3494, i checked other queries and noticed that
BlockJoinQuery currently throws UOE for getBoost and setBoost:
{noformat}
throw new UnsupportedOperationException("this query cannot support boosting;
please use childQuery.setBoost instead");
{noformat}
I don't think we can safely do that in queries, because other parts of lucene
rely upon this working... for example BQs rewrite when
it has a single clause and erases itself.
So I think we should just pass down the boost to the inner weight.
