Uwe Schindler commented on LUCENE-2514:
---------------------------------------
Robert: I can take MTQ tomorrow. I think we can remove the whole backwards
stuff from MTQ and change completely to BytesRef (internally). This makes the
steps TermsEnum (bytes) -> TermCollector -> TermQuery which converts all the
time simplier. The collector abstract class in the MTQ rewrites will be much
nicer.
I can also remove the rest of pre-BoostAttribute stuff from TopTermsRewrite.
I will go to sleep now, tomorrow more...

> in LUCENE-2426, the sort order was changed to codepoint order.
> unfortunately, Term is still using string internally, and more importantly
> its compareTo() uses the wrong order [utf-16].
> So MultiTermQuery, etc (especially its priority queues) are currently wrong.
> By changing Term to use bytes, we can also support terms encoded as bytes
> such as numerics, instead of using
> strange string encodings.
