Subject [jira] Updated: (LUCENE-489) Allow QP subclasses to support Wildcard Queries with leading "*"
Date Tue, 03 Oct 2006 23:14:22 GMT
     [ http://issues.apache.org/jira/browse/LUCENE-489?page=all ]

Steven Parkes updated LUCENE-489:
---------------------------------

    Attachment: LUCENE-489.patch

I was looking in this area (wildcard prefixes) so I figured I might as well do the cleanup.

Dan's patch, with newly generated javacc-3.2 files. Also added test cases, bothw/ and w/o
wildcard prefixes enable.

Includes patches to the javacc files generated from javacc-3.2 (but see also LUCENE-667).

> It would be usefull for some users if the logic that prevents QueryParser from creating
WIldcardQueries with leading wildcard characters ("?" or "*") be moved from the grammer into
the base implimentation of getWildcardQuery so that it may be overridden in subclasses without
needing to modifiy the grammer directly.
