I was just wondering if anyone has come across anything offering similar search functionality for mongoid as meta-search/ransack? During my searches I came across this mongoid group thread which mentioned sunspot_mongoid. I only had a quick look at it but my impression is that it doesn't quite offer the same view level helpers as meta-search which is really what I'm looking for
There are no project actually to do the same than meta_search on Mongoid gem. But there are a open issue about support Mongoid on meta_search maybe you can follow it.
About sunspot_mongoid it's a gem to wrap your Mongoid to a solr search engine. It's really not related to job do by meta_search
There are no feature request about support Mongoid on ransack.
