Subject [jira] [Commented] (SOLR-3652) Range Faceting will infinite loop if gap is too small relative to lower bounds of range (underflow occurs on add)
Date Wed, 25 Jul 2012 04:00:37 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3652?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13421985#comment-13421985
] 

Nicholas Jakobsen commented on SOLR-3652:
-----------------------------------------

Ah, I see, it's a problem of scale between the range and the gap. I'll try a double instead.
The reason for the large numbers is I'm storing UTC times for dates far in the past, e.g.
5000 BCE.

Thanks for the quick response!
