> In LUCENE-1536, Uwe suggested using FilteredQuery under-the-hood to implement filtered
search.
> But this query is inefficient, it does a per-document multiplication (wrapped.score()
* boost()).
> Instead, it should just pass the boost down in its weight, like BooleanQuery does to
avoid this per-document multiply.
