Hi there
I need help to understand how to run post filter scripts to show only results with cardinality \> 2.
{ "aggs" : { "products\_items" : { "term": { "field": "product" } },
"aggs" : { "distinct\_pricing" : { "cardinality" : { "field" : "price\_types" } } },
"post\_filter": {"script": {"script": "distinct\_pricing[price\_type].value \> 2 "}}} } } }
Basically with we have products\_items with many pricing types ;eg for VIP customers, VVIP customers & normal customers then we are interested to show only those items.
product\_items price\_type
001 VIP
001 VVIP
001 ORD
002 ORD
003 VIP
003 VVIP
004 VIP
005 ORD
005 VIP
Appreciate any help guidance.
Cheers

`post_filter` is only about top hits, not aggregations. What you are looking after is the bucket selector aggregation: [https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-pipeline-bucket-selector-aggregation.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-pipeline-bucket-selector-aggregation.html)

Thank you very much, Finally got it working -
I have pasted the sample query hopefully will be useful to others who encounter such a problem.
{
"aggs": {"ID1": {"terms": {"field": "cars"},
"aggs": {"ID2": {"cardinality": {"field": "roadaccessed"}},
"bucketfilter": {"bucket\_selector": { "buckets\_path" : { "cnt":"ID2"}, "script": "cnt\>5" }}}}} }
This will give you a list of cars that have accessed more than 5 roads
