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: search_cop_grammar.rb
    path of file: ./repos/search_cop/lib
    
    the code of the file until where you have to start completion: require "search_cop_grammar/attributes"
require "search_cop_grammar/nodes"

module SearchCopGrammar
  class BaseNode < Treetop::Runtime::SyntaxNode
    attr_writer :query_info, :query_options

    def query_info
      (@query_info ||= 
    
    def evaluate
      queries = query_info.scope.reflection.default_attributes.keys.collect { |key| collection_for key }.select { |collection| collection.compatible? text_value }.collect { |collection| collection.matches text_value }

      raise SearchCop::NoSearchableAttributes if queries.empty?

      queries.flatten.inject(:or)
    end
