if you are inside solr, as it seems to be the case, you can do this
QParserPlugin qplug =
req.getCore().getQueryPlugin(LuceneQParserPlugin.NAME);
QParser parser = qplug.createParser("PATIENT_GENDER:Male OR
STUDY_DIVISION:\"Cancer Center\"", null, req.getParams(), req);
Query q = parser.parse();
maybe there is a one-line call to get the parser from solr core, but i
can't find it now. Have a look at one of the subclasses of QParser
