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

     [ https://issues.apache.org/jira/browse/LUCENE-4777?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

André  updated LUCENE-4777:
---------------------------

    Description: 
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}
