Shai Erera updated LUCENE-4580:
-------------------------------
Attachment: LUCENE-4580.patch
Patch addresses the following:
* Add tests to DrillDownTest that verify that scores are not affected when
running drill-down queries.
* Fix DrillDown.query to return CSQ with boost set to 0.0f, as well as creating
the BQ with disable coord (thanks Uwe for the recommendations !)
* Improved DrillDown javadocs, as well as removed DrillDown.query() which took
no FacetSearchParams -- faceted search applications must work with
FacetSearchParams, even if the default one.
> Facet DrillDown should return a ConstantScoreQuery

> DrillDown is a helper class which the user can use to convert a facet value
> that a user selected into a Query for performing drill-down or narrowing the
> results. The API has several static methods that create e.g. a Term or Query.
> Rather than creating a Query, it would make more sense to create a Filter I
> think. In most cases, the clicked facets should not affect the scoring of
> documents. Anyway, even if it turns out that it must return a Query (which I
> doubt), we should at least modify the impl to return a ConstantScoreQuery.
