Penumbra

Just a shadow of sunspot/solr/whathave you. Creates JSON-stored Indexes, possibly collected into Catalogs. Really, it's just a bunch of hashes. Hashes all the way down! Hashes, I say!

Add this line to your application's Gemfile:

gem 'penumbra'

And then execute:

$ bundle

Or install it yourself as:

$ gem install penumbra
