Hi Guy,  
I am thinking of using an Elasticsearch query to display documents where the value of Field 1 equals Field 2. Does Elasticsearch support this type of query? If anyone knows, please provide me with more details. Thank you!  
?

I think that the only way is by using a script query.

Can you provide me with an example query that displays documents where two fields, `Field1` and `Field2` , have the same value? thanks you

I did not test it but according to [the doc](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-script-query.html), that should be something like:

```auto
GET /_search
{
  "query": {
    "bool": {
      "filter": {
        "script": {
          "script": """
            return (doc['Field1'].value == doc['Field2'].value);
          """
        }
      }
    }
  }
}

```

"As far as I know, how does Logstash configure to follow a query containing a script in it? To trigger and retrieve the fields I need, if you know, please share with me.

Is there a script to customize in an Elasticsearch query that can take field 1 from document 1 and compare it with the value of field 2 in document 2? Help me

Not really. That'd be "a join"... And Elasticsearch is not a relational DB.
