You can, but why would you use that?  
There is `http_poller`, or metricbeat or other, better options.

Thanks for reply...Actually I want to use update\_by\_query API which Kibana code given below:  
POST sam/products/\_update\_by\_query  
{  
"query" : {  
"constant\_score" : {  
"filter" : {  
"term" : {  
"title" : "redmi note 4"  
}  
}  
}  
},  
"script" : {  
"lang":"painless",  
"source" : "ctx.\_source.frequency++"

}  
}

I dont know how to run through logstash conf....if you have any sample...it's will be very useful...Below is my logstash query conf...file but I dont know how to use update\_by\_query API..so I am thinking to use curl in logstash..

input {  
elasticsearch {  
hosts =\> "localhost:9200"  
index =\> "queryindex"  
query =\> '  
{  
"query" : {  
"term" : {  
"tags" : "solr"  
}  
}}'  
}  
}  
output {  
stdout{  
codec =\> rubydebug  
}  
csv {  
fields =\> ["id"]  
path =\> "/root/sam/csv-export1.csv"  
}  
}

Any suggestion you want to give ....

Thank you.

The query in the input looks for solr, but the update is for phones though?

Hi Shekhar,

I don't think you need to use the update by query option.

Please have a look at:

[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)

Regards,

Not required. Just use the elasticsearch output and mention the action as update instead of index.
