Subject [jira] Commented: (SOLR-2429) ability to not cache a filter
Date Tue, 15 Mar 2011 19:40:30 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2429?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13007122#comment-13007122
] 

Yonik Seeley commented on SOLR-2429:
------------------------------------

The annoying part here is we need more metadata than just "Query" that we use now for a filter.
Unfortunately, SolrIndexSearcher uses List<Query> everywhere.

We could create something like a SolrQuery extends Query that wrapped a normal query and added
additional metadata (like cache options).  That's a bit messier since we'd have instanceof
checks and casts everywhere though.

Another option is to create a SolrQuery class that does not extend Query - hence methods taking
List<Query> would now need to take List<SolrQuery>

{code}
class SolrQuery {
  Query q;
  QParser qparser;
  boolean cache;
  ...
}
{code}

Thoughts?
