[jira] Commented: (LUCENE-2551) change jdk & icu collation to use byte[]

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

    [ https://issues.apache.org/jira/browse/LUCENE-2551?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12890260#action_12890260 ] 

Robert Muir commented on LUCENE-2551:
-------------------------------------

I looked at some of the keys in the test code, and encoding directly as byte results in keys nearly 1/2 the size (in bytes) of the previous encoding.

> Now that term is byte[], we should switch collation to use byte[] instead of 'indexablebinarystring'.
> This is faster and results in much smaller sort keys.
> I figure we can work it out here, and fix termrangequery to use byte in parallel, but we can already test sorting etc now.
