> When doing a Grouping search in solr cloud you can get a negative number for the total found.
> This is caused by the accumulated total being held in an integer and not a long.
>  
> example result:
> {{{ "responseHeader": { "status": 0, "QTime": 9231, "params": { "q": "decade:200", "indent": "true", "fl": "decade", "wt": "json", "group.field": "decade", "group": "true", "_": "1542773674247" } }, "grouped": { "decade": { "matches": -629516788, "groups": [ { "groupValue": "200", "doclist": { "numFound": -629516788, "start": 0, "maxScore": 1.9315376, "docs": [ { "decade": "200" } ] } } ] } } }}}
