             Summary: Caching of ReversedWildcardFilterFactory in SolrQueryParser looks broken
                 Key: SOLR-3492
                 URL: https://issues.apache.org/jira/browse/SOLR-3492
             Project: Solr
          Issue Type: Bug
          Components: search
    Affects Versions: 3.6, 4.0
            Reporter: Michael Ryan
            Priority: Minor


The caching of ReversedWildcardFilterFactory in SolrQueryParser looks broken.

Here's the current code:
{code}ReversedWildcardFilterFactory fac = leadingWildcards.get(fieldType);
if (fac == null && leadingWildcards.containsKey(fac)) {
  return fac;
}{code}

That doesn't quite make sense - fac will never be returned, as leadingWildcards will never contain a null key. I think this is probably what was intended:
{code}ReversedWildcardFilterFactory fac = leadingWildcards.get(fieldType);
if (fac != null) {
  return fac;
}{code}
