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

["Akos Kitta (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-4824?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13628728#comment-13628728 ] 

Akos Kitta commented on LUCENE-4824:
------------------------------------


Despite of several bug fixes in the join module for the 4.2. release, I still have different results for the same query time joining when the fields are stored as string and long.

I've already looked into the issue but stuck at 
{noformat} org.apache.lucene.search.MultiTermQueryWrapperFilter.getDocIdSet(AtomicReaderContext, Bits){noformat}
I've noticed that an irrelevant document ID is collected with the {noformat}org.apache.lucene.search.join.TermsQuery.SeekingTermSetTermsEnum{noformat} to the bitset.
I'm quite eager to contribute some kind of solution if someone could give me some advice or pointer.
Thanks is advance!

> 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.
