> MultiTermQuery has a TopTermsScoringBooleanRewrite, that uses a priority
> queue to expand the query to the top-N terms.
> currently N is hardcoded at BooleanQuery.getMaxClauseCount(), but it would be
> nice to be able to set this for top-N MultiTermQueries: e.g. expand a fuzzy
> query to at most only the 50 closest terms.
> at a glance it seems one way would be to expose TopTermsScoringBooleanRewrite
> (it is private right now) and add a ctor to it, so a MultiTermQuery can
> instantiate one with its own limit.
