  // If dealing with features or stale data or whatever, we might already have
  // settings stored for this index. If we have, we should take care to only
  // change what is needed, so we don't discard indexed data unnecessarily.
  // The easiest way to do this is by just pretending the index was already
  // present, but its fields were updated.
