Subject [jira] Commented: (LUCENE-2541) NumericRangeQuery errors with endpoints near long min and max values
Date Fri, 16 Jul 2010 23:35:53 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2541?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12889407#action_12889407

Yonik Seeley commented on LUCENE-2541:
--------------------------------------

Uwe I & discussed some on IRC, but for others following along, I believe the original
patch (checking for overflow) will generate the same ranges as BigIneger use would.

Here's the logic for the overflow case: nextMaxBound always either stays the same or decreases.
If nextMinBound does overflow a long, then if we had been using BigInts, it would be bigger
than MAX_LONG, and thus the "nextMinBound>nextMaxBound" condition would be satisfied to
break out of the loop.  Thus, "nextMinBound>nextMaxBound" using Bigints, is equivalent
to "nextMinBound>nextMaxBound || lowerWrapped" using longs.

The same logic applies to the lower bound.
