Subject [jira] [Commented] (SOLR-7219) Access filter cache from lucene query syntax
Date Sat, 08 Aug 2015 15:14:46 GMT

    [ https://issues.apache.org/jira/browse/SOLR-7219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14663011#comment-14663011

Yonik Seeley commented on SOLR-7219:
------------------------------------

I've temporarily disabled the test.  At first glance it looks like Lucene's Filter->Query
transition introduced a back-compat break.

> A filter query retrieves a set of documents matching a query from the filter cache. Since
scores are not cached, all documents that match the filter produce the same score. Cached
filters will be extremely fast when they are used again in another query.
> Filter Query Example:
> {code}
> description:HDTV OR filter(+promotion:tv +promotion_date:[NOW/DAY-7DAYS TO NOW/DAY+1DAY])
> {code}
> The power of the filter() syntax is that it may be used anywhere within a lucene/solr
query syntax. Normal fq support is limited to top-level conjunctions.
