John Wang commented on LUCENE-5327:
-----------------------------------

Hi Uwe and Robert for the feedback. I like the API giving hint about 
performance impacts.

What do you think about the IndexSearcher API providing acess to docvalues? 
Currently, calls such as document() and termVector() can be more expensive.

Thanks

John
