Shawn Heisey commented on SOLR-7495:
------------------------------------
A question for everyone having this problem ... is your numeric field defined
with docValues="true"? Does your index contain multiple shards? The error
message in the original report shows that Fabio's index *is* sharded, and the
schema shows that the field in question did *not* have docValues.
I suspect that if you add docValues, which *will require a reindex*, that the
problem might go away. The problem also might only exist on a multi-shard
(distributed) index.
See SOLR-8088. The field I was trying to group on is a text field, not
numeric, but docValues might also fix this problem. Since this issue is about
a numeric field, there's no need to worry about things like lowercasing.
Adding docValues makes sorting, faceting, and grouping use less memory, and
also usually makes them faster. It also makes the index larger.
