Subject Re: Recommendations for how to do faceted search in CouchDB
Date Wed, 30 Mar 2011 03:13:32 GMT
You can do that with a single view:

In the map, emit for each field key [fieldname,fieldvalue] and value null.
In the reduce, set it to '_count' (instead of a js function) to use the 
fast built-in reduce.

Then you can query that view with 
startkey=[fieldname]&endkey=[fieldname,{}]&group=true to see all the 
values in that field.

You don't really need _count, but that might be useful if you wanted to 
have some minimum of how many times a term is used before you include it.
