Subject [jira] [Commented] (LUCENE-6268) Replace doc values filters with queries having approximations
Date Fri, 20 Feb 2015 14:40:12 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-6268?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14328984#comment-14328984

Robert Muir commented on LUCENE-6268:
-------------------------------------

OK I agree, lets just deprecate them as-is for now.

On a followup issue, maybe we can allow a similar api to be exposed on query/weight/scorer,
so that booleanquery can do the optimizations filteredquery and booleanfilter are doing (any
optimizations that really help and not hurt). If we did this, then I think we could remove
the duplicate impls.

> We should use approximations in order to deal with queries/filters that have slow iterators
such as doc-values based queries/filters.
