Alan Woodward updated LUCENE-4883:
----------------------------------
Attachment: LUCENE-4883.patch
New patch, copying the uninvert logic from FieldCacheImpl into a new Uninverter
class (I haven't worked out how to implement the NumericDocValues uninverter
yet - pointers welcome), adding a cache to the UninvertingFilterReader itself
and checking uninversions against a map of fieldnames to DocValuesTypes passed
in as a constructor argument.
