Yes, by adding fq back into the main query you will get results increasingly filtered each time.
You may run into an issue if you are displaying facet counts, as the facet part of the query will also obey the increasingly filtered fq, and so not display counts for other categories anymore from the chosen facet (depends if you need to display counts from a facet once the first value from the facet has been chosen if you get my drift). Local params are a way to deal with this by not subjecting the facet count to the same fq restriction (but allowing the search results to obey it). -----Original Message----- From: Nguyen, Vincent (CDC/OD/OADS) (CTR) [mailto:v...@cdc.gov] Sent: Mon 04/10/2010 16:34 To: solr-user@lucene.apache.org Subject: RE: multi level faceting Ok.

In Solr PHP I would do that with, e.g. $params['facet'] = true; $params['facet.fields'] = array('Size'); $params['fq'] => array('sex' => array('Men', 'Women')); but yes i think you'd have to send through what the current facet query is and add it to your next drill-down On Oct 4, 2010, at 9:36 AM, Nguyen, Vincent (CDC/OD/OADS) (CTR) wrote: > Hi, > > > > I was wondering if there's a way to display facet options based on > previous facet values.
