I think this result is to be expected if you have some user IDs that match
both criteria? Eg. if your index has these two documents:
{
"UserId" : 42,
"State": "thing"
}
{
"UserId" : 42,
"State": "anything"
}
Then your aggregations would look like:
"aggregations": {
"total_distinct_count": {
"value": 1
},
"does_not_have_thing": {
"doc_count": 1,
"distinct_count": {
"value": 1
}
},
"has_thing": {
"doc_count": 1,
"distinct_count": {
"value": 1
}
}
}
And the sum of the values of distinct_count per bucket is larger than the
global value for distinct_count.
