> Two-phase support currently works for both sloppy and exact Scorers but it does not work if you have multiple terms at the same position (MultiPhraseQuery).
> This is because UnionPostingsEnum.nextDoc() aggressively reads and merges all the positions. Even making this initialization lazy might just be enough?
