Subject [jira] Created: (LUCENE-1291) Allow leading wildcard in table searcher
Date Tue, 20 May 2008 10:12:55 GMT
Allow leading wildcard in table searcher
----------------------------------------

                 Key: LUCENE-1291
                 URL: https://issues.apache.org/jira/browse/LUCENE-1291
             Project: Lucene - Java
          Issue Type: Wish
    Affects Versions: 2.3.1
            Reporter: Peter Backlund
            Priority: Minor


It would be nice to have a boolean property on TableSearcher for allowing leading wildcard
in query, which could be off by default.

            MultiFieldQueryParser parser = new MultiFieldQueryParser(fields, analyzer);
            parser.setAllowLeadingWildcard(this.allowLeadingWildcard);
            Query query = parser.parse(searchString);

+ setter and field for "allowLeadingWildcard"

Snippet is from http://www.koders.com/java/fid94A4BBC5CC6609930A88583480AA66B32EBB08E3.aspx?s=TableSearcher#L53,
lines 245-246.



Another approach would be to have a protected factory-method for creating the parser, which
can be overridden:

protected Parser createParser(fields, analyzer) {
  return new MultiFieldQueryParser(fields, analyzer);
} 

and 

  Query query = createParser(fields, analyzer).parse(searchString);
