-----------------------------------------

Thanks [~jim.ferenczi]. I was wondering if there is any reason why we don't put all this comparison logic (scores, keys, docIds) inside `SuggestScoreDoc::compareTo`, and then just use `a.compare(b)`, where `a` and `b` are `SuggestScoreDoc`?

> Today the completion suggester uses the document id to tiebreak completion suggestion with same scores. It would improve the stability of the sort to use the surface form of suggestions as the first tiebreaker.
