Yonik Seeley commented on SOLR-1223:
------------------------------------
The hardest part to this is passing the information through the Solr APIs to
tell Solr to cache the clauses of a particular boolean query separately.
2 approaches:
- a SolrQuery that wrapps a normal Query and adds extra metadata like "cache
separately" or "don't cache"
- replace Query with SolrFilter (that contains a Query as well as the extra
metadata)... involves many deprecations.

> Key: SOLR-1223
> URL: https://issues.apache.org/jira/browse/SOLR-1223
> Project: Solr
> Issue Type: New Feature

> Reporter: Brian Pearson
> Priority: Minor

> See this
> [issue|http://www.nabble.com/Query-Filter-fq-with-OR-operator-td23895837.html]
> for some background. Today, all of the Query filters specified with the
> fq parameter are AND'd together.
> This issue is about allowing a set of filters to be OR'd together (in
> addition to having another set of filters that are AND'd). The OR'd
> filters would of course be applied before any scoring is done.
> The advantage of this feature is that you will be able to break up complex
> filters into simple, more cacheable filters, which should improve performance.
