For a document containing all the phrase query terms, compute the frequency of the phrase in that document. A non zero frequency means a match. Note, that containing all phrase terms does not guarantee a match - they have to be found in matching locations.

Returns: frequency of the phrase in current doc, 0 if not found.

Implements Lucene::PhraseScorer.
