Subject [jira] Updated: (LUCENE-2514) Change Term to use bytes
Date Fri, 25 Jun 2010 10:49:49 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-2514?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Uwe Schindler updated LUCENE-2514:
----------------------------------

    Attachment: LUCENE-2514-MTQPagedBytes.patch

Improved version of PagedBytes MTQ cut off collector. It adds a method to PagedBytes.Reader
to sequentially read all BytesRefs without a separate offset array.

Mike, if you are fine with that, we should add this to the global patch for this issue.

We should maybe also fix PagedBytes.freeze(boolean), as the parameter is currently unused.
For the use case here, reallocating the last block is not really needed, it can stay as is.
Maybe we should readd support for this parameter.

> 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.
