Hi,  
actually, into different indexes, I have duplicated records which have the same field's values but, obviously, different `_id` value.  
so, trying to remove these duplicated records this is what I would like to do:

1. query a specific index
2. compare each found record with the others located inside index above
3. if `myfield` record's value1 is equal to `myfield` record's value2 drop record1

essentially, writing this procedure in a generic scripting language it will looks like:

```
foreach element into index.2017.06.6 {
     do {
        if element.myvalue equal element[+1].myvalue{
           delete element    
         }
      }
}

```

can someone help me? I don't want the code to do that, I would like to have some guidelines to understand the mechanism behind the execution of scripts and how can I pass parameters inside my search.

thanks

You won't be able to do this within a search script, since the script can only decide if a document matches the search, not try to remove a document at the same time. I think you will need to do this from your client. I don't think you will need an elasticsearch script though. It should just be a normal query, look at the results with the pseudocode you already have above, and if you find the condition you are looking for, issue a delete request for that document.

I mean from your application, which is using some client (whether eg an elasticsearch client or using http directly).

I feel myself really stupid.  
actually this is my structure

1. one script is extracting data to fill a file called MyFile
2. filebeat reads MyFile
3. filebeat sends read records to Logstash
4. Logstash normalize them and sends them to Elastic
