Cant we use scripted fields in dev console to perform any operations in elastic search

[PRUDHVI_CHOWDHARY_NE (Prudhvi Chowdhary Nekkalapudi)]

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")
while i am executing this none of them is deleting.

output in kibana dev console:

{
"took" : 0,
"timed_out" : false,
"total" : 0,
"deleted" : 0,
"batches" : 0,
"version_conflicts" : 0,
"noops" : 0,
"retries" : {
"bulk" : 0,
"search" : 0
},
"throttled_millis" : 0,
"requests_per_second" : -1.0,
"throttled_until_millis" : 0,
"failures" :
}
