I have a scripted field(named as exit_time) created by me.
Now i want to use this exit_time in dev console(kibana) to perform certain operations like delete,etc on documents present in the my index of elastic search.

How can i do this?Is it possible.

This is the query , i am trying in dev console of kibana

POST fqedup1/_delete_by_query?routing=1
{
"query": {
"range" : {
"difference" : {
"gte" : 17891245689
}
}
}
}

Here "difference" is a script field created by me (of type "number")
