Recover accidentally deleted index without snapshot

I was trying to delete a particular record, but I have accidentally deleted the entire index(rnd_prod). Below is the code I used to delete.

DELETE /rnd_prod/
   "query": {

      "ids": {
         "type": "rnd_prod",
         "values": [


I feel hopefull though because It seems elasticSearch doesnt physically delete the data immediately, until something called merging happens(reference).

Please help.. I donot have any backups/snapshots of this index..

You're out of luck here unfortunately.
