Relevance always returning 1.0

[mysticaltech]

Hello folks,

First of all thank you for your good work.

To make this gem work with the latest mongoid, I needed to use this branch:
gem 'mongoid_search', git: 'git://github.com/sivagollapalli/mongoid_search.git', branch: 'mongoid_rc_support'

I think it's already in your pipeline to merge with your master.

The search works as expected however I am getting an issue with relevance value, it always comes as 1.0 for all results for whatever query I input.

I am searching in 3 Strings fields:

search_in :name, :name_refined, :short_description

And using full_text_search('keyword')

My config in config/initializers/mongoid.rb is as follows:

require 'lingua/stemmer'

Mongoid.raise_not_found_error = false

Mongoid::Search.setup do |config|
  config.match = :any
  config.allow_empty_search = true
  config.relevant_search = true
  config.stem_keywords = true
  config.stem_proc = Proc.new { |word| Lingua.stemmer(word, :language => 'en') }
  config.ignore_list = YAML.load(File.open(Rails.root.to_s + '/config/ignorelist.yml'))["ignorelist"]
  config.regex_search = true
  config.ligatures = { "œ"=>"oe", "æ"=>"ae" }
  config.minimum_word_size = 2
end

Any idea what might be causing my relevancy to always be 1.0 ?

Thanks
