[jira] [Commented] (LUCENE-3256) Consolidate CustomScoreQuery,
ValueSourceQuery and BoostedQuery
[ https://issues.apache.org/jira/browse/LUCENE-3256?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13056908#comment-13056908 ]
Chris Male commented on LUCENE-3256:
------------------------------------
As part of this, I am going to move the seemingly useful FieldScoreQuery to the new module too and change it to work with FunctionQuery and the new ValueSources.

> Lucene's CustomScoreQuery and Solr's BoostedQuery do essentially the same thing: they boost the scores of Documents by the value from a ValueSource. BoostedQuery does this in a direct fashion, by accepting a ValueSource. CustomScoreQuery on the other hand, accepts a series of ValueSourceQuerys. ValueSourceQuery seems to do exactly the same thing as FunctionQuery.
> With Lucene's ValueSource being deprecated / removed, we need to resolve these dependencies and simplify the code.
> Therefore I recommend we do the following things:
> - Move CustomScoreQuery (and CustomScoreProvider) to the new Queries module and change it over to use FunctionQuerys instead of ValueSourceQuerys.
> - Deprecate Solr's BoostedQuery in favour of the new CustomScoreQuery. CSQ provides a lot of support for customizing the scoring process.
> - Move and consolidate all tests of CSQ and BoostedQuery, to the Queries module and have them test CSQ instead.
