Filtering on Script Value

Elastic Stack Elasticsearch
1

I'm trying to calculate a value for each hit then select or filter on a
calculated value. Something like below:

"query": {
    "match_all": {}
    },
    "script_fields" : {
        "counter" : {
            "script" : "count++",
            "params" : {
                "count"  : 1
            }
        },
        "source" : {
          "script" : "_source"
    }
  }

I'd like to filter on the count parameter.

I've read on a StackOverflow post that you cannot filter on a script value.

So is there another way to calculate some value dynamically and filter on
that value?

If not, is there a nested SQL SELECT equivalent in ElasticSearch? Maybe I
could execute the first query to calculate the 'count' then execute another
query to filter by a value?

Hello,

You should be able to filter with a script using the script filter:

I've tried that with this query:

GET leases_allv2/_search
{
"query": {
"filtered": {
"filter": {
"and": [
{
"or": [
{
"term": {
"states": "co"
}
}
]
},
{

    "script" : {
        "script" : "count++; count <= 3",
        "params" : {
            "count" : 0
        }
    }
      }
    ]
  }
  
}

}
}

But what happens with that query is since I have 5 shards on our database,
I get 15 results back. So the counter variable is getting reset for each
shard.

Is there a way to keep that counter from resetting when searching each
shard?
