I already have index in elasticsearh, i added new field in logstash to my index like the follow:

mutate {

```
                    add_field => {"[location]" => ["%{lat}","%{lon}"]}
               }

         mutate {
                 convert => {
                             "[location][lat]" => "float"
                             "[location][lon]" => "float"
                            }

```

I found the new field as i want but i couldn't map the location to be geo\_point  
Any suggestions ?  
Thanks
