Mark Miller updated LUCENE-1483:
--------------------------------

    Description: FieldCache and Filters are forced down to a single segment reader, allowing for individual segment reloading on reopen.  (was: Here is a quick test patch. FieldCache for sorting is done at the individual IndexReader level and reloading the fieldcache on reopen can be much faster as only changed segments need to be reloaded.)
        Summary: Change IndexSearcher to use MultiSearcher semantics for multiple subreaders  (was: Change IndexSearcher to use MultiSearcher semantics for sorted searches)
