[jira] [Closed] (LUCENE-6252) Numeric range search does not find
all expected results
[ https://issues.apache.org/jira/browse/LUCENE-6252?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Slav Boleslawski closed LUCENE-6252.
------------------------------------
Resolution: Not a Problem
Fix Version/s: 4.10.3
My mistake based on some obsolete LongField documentation: the default precision step is 16 rather than 4 as the doco text suggests.
