Subject Re: Recommendations for how to do faceted search in CouchDB
Date Fri, 01 Apr 2011 00:09:52 GMT
For searching for an arbitrary set of conditions on fields, you will 
want to use a search component like couchdb-lucene.

It's not just useful for full-text search; if you have a bunch of 
parameters that you want to filter on, your lucene view can look like:

function(doc) {
	var ret = new Document();
	if (foo in doc) ret.add(,{"field":"foo","index":"not_analysed");
	if (bar in doc) ret.add(,{"field":"bar","index":"not_analysed");

	return ret;

Then your query can look like q="foo:5 OR bar:Sydney".
Full-text search indices can live alongside not_analysed indexes too, so 
you can use for each whatever makes sense.
