title: CouchDB Views: created_at greater than a passed value
body: <p>I'm trying to write a couchdb view that takes a created_at timestamp in a sortable format (2009/05/07 21:40:17 +0000) and returns all documents that have a greater created_at value.</p>
  
  <p>I'm specifically using couch_foo but if I can figure out how to write the view I can create it in futon or in the couch_foo model instead of letting couch_foo do it for me.</p>
  
  <p>I've searched all around and can't figure out the map/reduce to do this, if it's possible.</p>
