[jira] [Updated] (LUCENE-4883) Hide FieldCache behind an UninvertingFilterReader

["Alan Woodward (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LUCENE-4883?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alan Woodward updated LUCENE-4883:
----------------------------------

    Attachment: LUCENE-4883.patch

New patch, with a NumericDocValues uninverter.  Also a basic test.

NumericDocValues doesn't work with 32-bit values yet (the test for IntField fails); I need to somehow detect at uninversion-time how wide the indexed values are.
