Subject [jira] Updated: (LUCENE-2514) Change Term to use bytes
Date Fri, 25 Jun 2010 16:58:52 GMT

     [ 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.patch

updated patch:
* dropped the range query/filter changes so we can refactor those separately.
* removed the BytesRef.EMPTY, uwe pointed out this is very dangerous since we cant prevent
someone from modifying it.
* tried to optimize preflex codec, removing more conversions and removing scratchbytesref
copying... i think more can be done here.
* merged in uwe's latest multitermquery changes.

> 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.
