[jira] Updated: (LUCENE-2514) Change Term to use bytes
[ https://issues.apache.org/jira/browse/LUCENE-2514?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Muir updated LUCENE-2514:
--------------------------------
Attachment: LUCENE-2514_collatedrange.patch
In order to move forward with collation-keys-as-byte and other improvements, we need to fix TermRangeQuery.
But this is difficult when the String-only Collation support exists mixed with the byte-order TermRangeQuery...
As discussed previously on this issue, here is a patch that splits this into a separate CollatedTermRangeQuery/Filter

> 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.
