[jira] Commented: (LUCENE-2514) Change Term to use bytes

["Robert Muir (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-2514?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12895579#action_12895579 ] 

Robert Muir commented on LUCENE-2514:
-------------------------------------

by the way, i was thinking it would be nice to really move this slow collatedtermrangequery stuff either out of lucene alltogether or at least into contrib/queries.

we could make things even better by removing queryparser's get/setRangeCollator method.
instead in its place, it could have something like a boolean 'analyzeRangeQueries' ?
it could then analyze the endpoints (producing byte collation keys) and use a regular fast term range query.

I think its good to support collation order for people who want it, but we should make it easy to do things the fast way, 
right now we make it easy to do things the slow way and hard to do it fast.

> 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.
