Picky Bug Report

gistfile1.rb

require 'picky'

Shoe = Struct.new(:id, :color, :name)

shoes_index = Picky::Index.new(:shoes) do
  category :color
  category :name
end

shoes_search = Picky::Search.new(shoes_index)

shoes_index.add Shoe.new(1, 'black', 'Outdoor Black')

shoes_search.facets(:color) #=> {'black' => 1}
shoes_search.facets(:color, filter: 'black') #=> {'black' => 2}

What if you search for

shoes_search.facets(:color, filter: 'color:black') # => {"black"=>1}
shoes_search.facets(:color, filter: 'name:black') # => {"black"=>1}

?

That's the reason the docs prefix a specific category for their filter:
http://pickyrb.com/documentation.html#search_facets

The idea is that you can filter against everything and that if you want to filter only on a specific category, you have to tell Picky to do so.

Also: Thanks for the gist file – very helpful!
