Tomás Fernández Löbbe commented on SOLR-8420: --------------------------------------------- bq. I wonder if DateStatsValues's private long sum = 0; might perhaps become double also (similar to NumericStatsValues's sum being a double already). Yes, I think it should. This should also change the output, currently it's a date like: {code:xml} <date name="sum">122366-06-12T21:06:06Z</date> {code} > Date statistics: sumOfSquares overflows long > -------------------------------------------- > > Key: SOLR-8420 > URL: https://issues.apache.org/jira/browse/SOLR-8420 > Project: Solr > Issue Type: Bug > Components: SearchComponents - other > Affects Versions: 5.4 > Reporter: Tom Hill > Priority: Minor > Attachments: 0001-Fix-overflow-in-date-statistics.patch, > 0001-Fix-overflow-in-date-statistics.patch, StdDev.java > > > The values for Dates are large enough that squaring them overflows a "long" > field.
