Sources are not passed in as second parameter for Index::Base anymore, but either
* as :source option:
  Index::Base.new(:some_index_name, source: some_source)
or
* given to the #source method inside the config block:
  Index::Base.new(:some_index_name) do
    source some_source
  end

Sorry about that breaking change (in 2.2.0), didn't want to go to 3.0.0 yet!

All the best
