How do you build an efficient PhraseScorer to work with an impact- sorted posting list?
The way PhraseScorer currently works is: find a doc that contains all terms, then see if the terms occur consecutively in phrase order, then determine a score. The TermDocs objects feeding PhraseScorer return doc_nums in ascending order, so finding an intersection is easy. But if the document numbers are returned in what looks to the PhraseScorer like random order... ??
