Subject [jira] Commented: (SOLR-106) new facet params: facet.sort, facet.mincount, facet.offset
Date Sun, 14 Jan 2007 16:01:27 GMT

    [ https://issues.apache.org/jira/browse/SOLR-106?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12464596
] 

Andreas Hochsteger commented on SOLR-106:
-----------------------------------------

What about a facet filter query to only return facets which match a certain query?

In our case we use categories which are organized hierarchically via a path syntax.
Documets have different categories attached which is indexed by a solr field.

Now certain apps (which deal with these documets) are interested in a specific category subpath.
If you use faceted searching you get all categories back - not only those in which the application
is interested in.

Currently we use a workaround which uses an additional solr search field that just contains
the categories for the application, but this doesn't scale very well.
Would it be possible to add an additional filter query for facets to limit the facets which
are actually returned in the faceted search?

Thoughts?

> a couple of new facet params:
> facet lists become pageable with facet.offset, facet.limit  (idea from Erik)
> facet.sort explicitly specifies sort order (true for count descending, false for natural
index order)
> facet.mincount: minimum count for facets included in response (idea from JJ, deprecate
zeros)
