Robert Muir updated LUCENE-1951:
--------------------------------
Attachment: LUCENE-1951.patch
patch for these issues.
note: the existing TestWildCardQuery.testTermWithoutWildcard had a bad test,
and needs to be fixed for bw-compat branch.
it did the following:
{code}
Query wq = new WildcardQuery(new Term("field", "nowildcard"));
wq = searcher.rewrite(wq);
assertTrue(wq instanceof TermQuery);
{code}
this is not correct, it should only be TermQuery when rewriteMethod is
SCORING_BOOLEAN_QUERY_REWRITE. and this is not the default, constant score is.
easiest way to fix the old test is to
setRewriteMethod(SCORING_BOOLEAN_QUERY_REWRITE), its the only time it should
rewrite to TermQuery.

> Project: Lucene - Java
> Issue Type: Improvement
> Components: Query/Scoring
> Reporter: Robert Muir
> Priority: Minor
> Attachments: LUCENE-1951.patch
>
>
> wildcardquery has logic to rewrite to termquery if there is no wildcard
> character, but
> * it needs to pass along the boost if it does this
> * if the user asked for a 'constant score' rewriteMethod, it should rewrite
> to a constant score query for consistency.
> additionally, if the query is really a prefixquery, it would be nice to
> rewrite to prefix query.
> both will enumerate the same number of terms, but prefixquery has a simpler
> comparison function.
