You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: index.rb
    path of file: ./repos/search_flip/lib/search_flip
    
    the code of the file until where you have to start completion: module SearchFlip
  # The SearchFlip::Index mixin makes your class correspond to an
  # Elasticsearch index. Your class can then create or delete the index, modify
  # the mapping, import records, delete records and query the index. This gem
  # uses an individual Elasticsearch index for each in
    
      def create(scope, options = {}, additional_index_options = {})
        bulk options do |indexer|
          each_record(scope, index_scope: true) do |object|
            indexer.create record_id(object), serialize(object), index_options(object).merge(additional_index_options)
          end
        end

        scope
      end
