[jira] Updated: (LUCENE-395) CoordConstrainedBooleanQuery + QueryParser support
[ http://issues.apache.org/jira/browse/LUCENE-395?page=all ]
Yonik Seeley updated LUCENE-395:
--------------------------------
Attachment: BooleanQuery.patch
TestBooleanMinShouldMatch.java
Thanks for the scoring clarification guys... if I only set minNrShouldMatch>0 on the top level query, all the scores match!
Changes:
- added BooleanQuery.getMinimumNumberShouldMatch()
- added the syntax Chris (Hoss) suggested to BooleanQuery.toString()... but it's not too late to change if someone has a better idea
- added random boolean query testing with variable minMrShouldMatch to TestBooleanMinShouldMatch
> CoordConstrainedBooleanQuery + QueryParser support

> Attached 2 new classes:
> 1) CoordConstrainedBooleanQuery
> A boolean query that only matches if a specified number of the contained clauses
> match. An example use might be a query that returns a list of books where ANY 2
> people from a list of people were co-authors, eg:
> "Lucene In Action" would match ("Erik Hatcher" "Otis Gospodnetić" "Mark Harwood"
> "Doug Cutting") with a minRequiredOverlap of 2 because Otis and Erik wrote that.
> The book "Java Development with Ant" would not match because only 1 element in
> the list (Erik) was selected.
> 2) CustomQueryParserExample
> A customised QueryParser that allows definition of
> CoordConstrainedBooleanQueries. The solution (mis)uses fieldnames to pass
> parameters to the custom query.
