[jira] [Commented] (LUCENE-4824) Query time join returns different results based on the field type

["Martijn van Groningen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-4824?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13678076#comment-13678076 ] 

Martijn van Groningen commented on LUCENE-4824:
-----------------------------------------------

Sorry for the late reply. A gave this some more thought and I think the primitive numbers (long, double, etc.) to ByteRef conversion isn't optimal. Instead I think having native primitive number based joining implementations would make more sense and expect it be faster then the current implementation.

> 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.
