Description
I'm experiencing different query time joining behavior based on the type of the 'toField' and 'fromField'. Basically I got correct results when both 'toField' and 'fromField' are StringField, but incorrect in case of LongField.

Research direction
Start with the attached QueryTimeJoinTest.java to reproduce the differing query-time join results for StringField and LongField, then review the attached LUCENE-4824.patch for the historical context. Done means query-time joins return consistent, correct results when the fields use LongField as well as StringField, with regression coverage for the reported case.
