Ivan Biggs commented on LUCENE-466:
-----------------------------------
After reviewing other GSoC 2014 tagged issues for LUCENE, I believe (due to the
relative simplicity of updating the query parsers) that it would be fairly
interesting and doable to work out LUCENE-4892 dur9ing my GSoC work this summer.
Thanks again,
Ivan
> Need QueryParser support for BooleanQuery.minNrShouldMatch

> Key: LUCENE-466
> URL: https://issues.apache.org/jira/browse/LUCENE-466
> Project: Lucene - Core
> Issue Type: Improvement
> Components: core/search
> Environment: Operating System: other
> Platform: Other
> Reporter: Mark Harwood
> Priority: Minor
> Labels: gsoc2014
>
> 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.
