Subject [jira] Updated: (LUCENE-1213) MultiFieldQueryParser ignores slop parameter
Date Mon, 10 Mar 2008 06:57:46 GMT

]

Doron Cohen updated LUCENE-1213:
--------------------------------

    Attachment: multifield-fix.patch

Trekaj thanks for the patch. 

Attached a slightly compacted fix (refactoring slop-applying to a separate method).
Also added a test that fails without this fix.

All tests pass, if there are no comments I will commit this in a day or two.

> MultiFieldQueryParser.getFieldQuery(String, String, int) calls super.getFieldQuery(String,
String), thus obliterating any slop parameter present in the query.
> It should probably be changed to call super.getFieldQuery(String, String, int), except
doing only that will result in a recursive loop which is a side-effect of what may be a deeper
problem in MultiFieldQueryParser -- getFieldQuery(String, String, int) is documented as delegating
to getFieldQuery(String, String), yet what it actually does is the exact opposite.  This also
causes problems for subclasses which need to override getFieldQuery(String, String) to provide
different behaviour.
