module Algolia
  module Search
    # Class Index
    class Index
      include CallType
      extend Forwardable # available in ruby 2.2
      
      attr_reader :index_name, :transporter, :config
      
      def_delegators :@tranporter, :read, :write
      
    end
  end
end

The instead of

def search(query, opts: {})
  @transporter.read(:POST, "#{@index_uri}/query", body: {'query': query}, opts: opts)
end
      
def batch(request, opts: {})
  @transporter.write(:POST, "#{@index_uri}/batch", body: request, opts: opts)
end

you simply write

def search(query, opts: {})
  read(:POST, "#{@index_uri}/query", body: {'query': query}, opts: opts)
end

def batch(request, opts: {})
  write(:POST, "#{@index_uri}/batch", body: request, opts: opts)
end
