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: query_facet.rb
    path of file: ./repos/sunspot/sunspot/lib/sunspot/dsl
    
    the code of the file until where you have to start completion: module Sunspot
  module DSL
    # 
    # This tiny DSL class implements the DSL for the FieldQuery.facet
    # method.
    #
    class QueryFacet
      def initialize(query, setup, facet, options) #:nodo
    
      def row(label, &block)
        query_facet = Sunspot::Query::QueryFacet.new(@options)
        Sunspot::Util.instance_eval_or_call(
          Scope.new(@query.add_query_facet(query_facet), @setup),
          &block
        )
        @facet.add_row(label, query_facet.to_boolean_phrase)
      end
