["Karl Wettin (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-839?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12668728#action_12668728 ] 

Karl Wettin commented on SOLR-839:
----------------------------------

The patch does not parse UTF8. Not sure if it is supposed to do that by default? Below is my version of the class. It needs to pick up the contentEncoding from the properties, but I'm not sure where and how.

{code:java}
import org.apache.solr.common.params.SolrParams;
import org.apache.solr.common.util.NamedList;
import org.apache.solr.request.SolrQueryRequest;
import org.apache.solr.search.QParserPlugin;
import org.apache.solr.search.QParser;
import org.apache.lucene.search.Query;
import org.apache.lucene.queryParser.ParseException;
import org.apache.lucene.xmlparser.CorePlusExtensionsParser;
import org.apache.lucene.xmlparser.ParserException;

import java.io.ByteArrayInputStream;
import java.io.UnsupportedEncodingException;

public class XmlQParserPlugin extends QParserPlugin {

  private String contentEncoding = "UTF8";

  public void init(NamedList args) {
  }

  public QParser createParser(String qstr, SolrParams localParams, SolrParams params, SolrQueryRequest req) {
    return new XmlQParser(qstr, localParams, params, req);
  }


  class XmlQParser extends QParser {
    public XmlQParser(String qstr, SolrParams localParams, SolrParams params, SolrQueryRequest req) {
      super(qstr, localParams, params, req);
    }

    public Query parse() throws ParseException {
      CorePlusExtensionsParser parser = new CorePlusExtensionsParser(getReq().getSchema().getQueryAnalyzer(), getReq().getSchema().getSolrQueryParser(null));
      try {
        return parser.parse(new ByteArrayInputStream(getString().getBytes(contentEncoding)));
      } catch (UnsupportedEncodingException e) {
        throw new ParseException(e.getMessage());
      } catch (ParserException e) {
        throw new ParseException(e.getMessage());
      }
    }
  }

}
{code}
