Hi,

I would like to prevent the same data log indexed twice.

I found out from the documentation that it can be achieved using "op\_type" parameter.

$ curl -XPUT '[http://localhost:9200/twitter/tweet/1?op\_type=create](http://localhost:9200/twitter/tweet/1?op_type=create)' -d '{  
"user" : "kimchy",  
"post\_date" : "2009-11-15T14:12:12",  
"message" : "trying out Elasticsearch"  
}'

However, how do you use "op\_type" in Logstash?

I am using filebeats to send data to logstash.  
In logstash, my data is parsed into JSON and sent to elastic search via the elasticsearch output plugin:

output {  
elasticsearch { hosts =\> ["localhost:9200"] }  
stdout { codec =\> rubydebug }  
}

Can I include op\_type=create in the output plugin? How, what is the syntax?

Thanks,  
Gunay

I think [https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-action](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-action) is what you are after.

Thank you very very much Mark. Indeed, it is it the action setting what I was looking for.
