Ian created SOLR-13004:
--------------------------
Summary: Integer overflow in total count in grouping results
Key: SOLR-13004
URL: https://issues.apache.org/jira/browse/SOLR-13004
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: search, SolrCloud
Affects Versions: 5.5.3
Reporter: Ian
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" } ] } } ] } } }}}
{{result without grouping:}}
