Mark Miller commented on LUCENE-1771:
-------------------------------------
bq. Actually, since QueryWeight is new in 2.9, we can simply make this change
w/o deprecation.
We do have to be back compat with Weight though - ugg - so QueryWeight would
somehow need to expose a deprecated working explain(IndexReader, int) ? ...
but if we could do that ...
> Using explain may double ram reqs for fieldcaches when using
> ValueSourceQuery/CustomScoreQuery or for ConstantScoreQuerys that use a
> caching Filter.
