Subject Re: Recommendations for how to do faceted search in CouchDB
Date Thu, 31 Mar 2011 17:30:47 GMT

I'm interested in that question too but a bit noob with CouchDB.

The goal of faceted search is to put conditions on several fields at a time, and get the union
of that set of conditions, right ?
then how would you do that in the query ?
