def _matches?(selector)
  # Opens a regexp budget for this document only. Callers that match many
  # documents against one selector open a budget of their own first, and
  # this one joins it rather than giving every document a fresh limit.
  Matcher::RegexpBudget.open(selector) do
    Matcher::Expression.matches?(self, selector)
