i ran the following aggregation
"aggs": {
"userdetails": {
"terms": {
"field": "userName"
},
"aggs": {
"infodetails": {
"cardinality": {
"field": "info"
}
}
}
}
}
with the above aggregation got the following results
"aggregations": {
"userdetails": {
"doc\_count\_error\_upper\_bound": 0,
"sum\_other\_doc\_count": 0,
"buckets": [
{
"key": "test1",
"doc\_count": 2,
"infodetails": {
"value": 2
}
},
{
"key": "test2",
"doc\_count": 1,
"infodetails": {
"value":1
}
}
]
}
}
if i want to restrict buckets based on cardinality value. what is the way?
for example in the above scenario i got 2 results one with value 1 and other with 2.
suppose i want to have buckets with cardinality more than 2?
this is the requirement i have, please let me know what can i use to achieve this
