Subject [jira] [Commented] (LUCENE-7111) DocValuesRangeQuery.newLongRange behaves incorrectly for Long.MAX_VALUE and Long.MIN_VALUE
Date Thu, 17 Mar 2016 13:43:33 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-7111?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15199531#comment-15199531

Robert Muir commented on LUCENE-7111:
-------------------------------------

and, if its an overflow in the logic that should not happen (looks like it might be), i think
its worth it to change the add/subtracts here to Math.addExact/Math.subtractExact.

> It seems that the following queries return all documents, which is unexpected:
> {code}
> DocValuesRangeQuery.newLongRange("dv", Long.MAX_VALUE, Long.MAX_VALUE, false, true);
> DocValuesRangeQuery.newLongRange("dv", Long.MIN_VALUE, Long.MIN_VALUE, true, false);
> {code}
> In Solr, floats and doubles are converted to longs and -0d gets converted to Long.MIN_VALUE,
and queries like {-0d TO 0d] could fail due to this, returning all documents in the index.
