Robert Muir updated LUCENE-2514:
--------------------------------
Attachment: LUCENE-2514_collatedrange.patch
just checkpointing progress, here's my latest patch.
Here i moved the slow functionality (range,sort) out of core and into
contrib/queries.
So TermRangeQuery just does byte comparison, nothing fancy.
Additionally TermRangeQuery's API is changed to be more like
NumericRangeQuery's, with newStringRange and newByteRange.
TODO:
* QP's newRangeQuery args should be changed to BytesRef, and newRangeQuery
should build ranges with newByteRange
* contrib/qp needs a new attribute and some other work, and some of the other
queryparsers need more changes too.
* need to add tests (the ones i removed from core) for SlowCollatedRangeQuery
and friends.

> 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.
