Subject [jira] [Created] (LUCENE-4777) NPE in MultiFieldQueryParser
Date Wed, 13 Feb 2013 17:10:13 GMT
André  created LUCENE-4777:
------------------------------

             Summary: NPE in MultiFieldQueryParser
                 Key: LUCENE-4777
                 URL: https://issues.apache.org/jira/browse/LUCENE-4777
             Project: Lucene - Core
          Issue Type: Bug
          Components: core/queryparser
    Affects Versions: 4.1
            Reporter: André 


The method getRegexpQuery() in MultiFieldQueryParser is not overridden.
That leads to RegexpQueries where field=null (see example below).

{code}
QueryParser qp = new MultiFieldQueryParser(Version.LUCENE_41, new String[]{ "content" }, new
StandardAnalyzer(Version.LUCENE_41)) 
qp.parse("path:foo/bar/foo"); // no ParseException thrown here
Assert.assertNotNull(((RegexpQuery)((BooleanQuery)q).getClauses()[1].getQuery()).getField())
{code}
