bq. I would temporary remove all String methods from Term and try to compile
core. If this works you should find all perf regressions in both directions.
i did this, but there is a lot of unrelated stuff that uses Term string methods
and is perfectly fine. especially many tests and things like queryparser.

Yeah tests can use string methods, i meant only core classes should compile
without Term's String methods.
bq. one option might be to split the collating range stuff into its own classes
or something, i think its a bit confusing how collation is mixed in with
'binary' order... it tricks you into thinking the 'default' is UCA or default
locale or something, but is neither.
I was always thinking about factoring out collation stuff from TermRangeQuery.
I would like to have a pure TermRangeQuery without any collations things and
maybe a CollationTermRangeQuery or whatever...

> 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.
