[jira] Commented: (LUCENE-1435) CollationKeyFilter: convert tokens into CollationKeys encoded using IndexableBinaryStringTools

["Michael McCandless (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-1435?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12683155#action_12683155 ] 

Michael McCandless commented on LUCENE-1435:
--------------------------------------------

I think we should commit this to contrib/collation as an "external" way to get faster range filters on fields that require custom Collator; at some future point we can consider allowing a given field to sort its terms in some custom way.

Marvin: does KS/Lucy give control over sort order of the terms in a field?

> Converts each token into its CollationKey using the provided collator, and then encodes the CollationKey with IndexableBinaryStringTools, to allow it to be stored as an index term.
> This will allow for efficient range searches and Sorts over fields that need collation for proper ordering.
