columns.
[ https://issues.apache.org/jira/browse/SOLR-3973?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alexandre Rafalovitch closed SOLR-3973.
---------------------------------------
Resolution: Incomplete
Ancient discussion about facet implementation options. If still relevant, a new issue should be created. Probably against the new JSON facet API.

> We often come across the scene of the multi-faceted cross, For example, the SQL statement, select count( * ) from table group by A,B.
> Now we slightly modified for FacetComponent, this component to be able to support the multi-faceted cross.you can facet on multiple columns, and get the count result of multi-faceted cross.
> Request parameters are as follows：
> &start=0&rows=0&q=*:*&facet=true&facet.field=user_city&facet.field=user_province&facet.limit=10&facet.cross=true&facet.cross.sep=,
> The original effect is as follows:
