> A generalized version of PhraseQuery, built with one or more MultiTermQuery
> that provides term expansions for multi-terms (one of the expanded terms must
> match).
> Its main advantage is to control the total number of expansions across all
> MultiTermQuery and across all segments.
> This query is similar to MultiPhraseQuery, but it handles, controls and
> optimizes the multi-term expansions.
>
> This query is equivalent to building an ordered SpanNearQuery with a list of
> SpanTermQuery and SpanMultiTermQueryWrapper.
> But it optimizes the multi-term expansions and the segment accesses.
> It first resolves the single-terms to early stop if some does not match.
> Then it expands each multi-term sequentially, stopping immediately if one
> does not match. It detects the segments that do not match to skip them for
> the next expansions. This often avoid expanding the other multi-terms on some
> or even all segments. And finally it controls the total number of expansions.
