Subject [jira] Commented: (SOLR-407) Uncached filter query parameters
Date Thu, 08 Nov 2007 16:45:50 GMT


Hoss Man commented on SOLR-407:

Mike: one thing that's not clear to me from a quick glance at your patch is wether or not
this case works...

   q= -foo & fq.nocache=bar

...i *think* that in your patch, a boolean query containing one negative foo clause gets added
to a new "target" query as a mandatory clause along with the fq.nocache ... and the SolrIndexSearcher
code for detecting a pure negative query and finding the inverse doesn't get tripped.

> Add a fq.nocache parameter (that may be specified multiple times) that adds filter clauses
to the query which are not cached.  Further, these filters are embedded directly into the
BooleanQuery, which should be more efficient when filters are not reused.
