def find_similar(options = {})
  search_similar(options).results.map {|x| x[:model] }
end

#search_similar(options = {}) ⇒ Object

The model classes to search are automatically generated off the classes of the entries in the array. If you want more control over which models to search, specify option :models and it will override the default behavior
