  # The "klass" function in the query classes is used only to determine what
  # type of search results to return (that is, which class the QueryResult
  # class will call "load_from_elasticsearch" on). Because the Pseud search
  # should always wrap Pseuds up in a PseudDecorator, we return PseudDecorator
  # instead of Pseud.
