Thank you!
It seems to me that I managed to get it work.
Just for future reference short I attach source code. The jar should be placed
under core/lib folder:
Please let me know if you have any comments or if I got sth incorrect...
public class PrecedenceQParserPlugin extends QParserPlugin {
private static final Logger LOG =
LoggerFactory.getLogger(PrecedenceQParserPlugin.class);
@Override
public void init(NamedList list) {
}
@Override
public QParser createParser(String qstr, SolrParams localParams,
SolrParams params, SolrQueryRequest req) {
LOG.debug("creating new PrecedenceQParser:", new Object[]
{qstr, localParams, params, req});
return new PrecedenceQParser(qstr, localParams, params, req);
}
}
class PrecedenceQParser extends QParser {
private static final Logger LOG =
LoggerFactory.getLogger(PrecedenceQParser.class);
private final PrecedenceQueryParser parser;
public PrecedenceQParser(String qstr, SolrParams localParams,
SolrParams params, SolrQueryRequest req) {
super(qstr, localParams, params, req);
this.parser = new PrecedenceQueryParser();
}
@Override
public Query parse() throws ParseException {
LOG.debug("parse(): ", qstr);
if (null==qstr) {
return null;
}
final String defaultField =
QueryParsing.getDefaultField(getReq().getSchema(),getParam(CommonParams.DF));
try {
return parser.parse(qstr, defaultField);
} catch (QueryNodeException e) {
throw new ParseException(e.getMessage(), e);
}
}
}
Best Regards
