[thilina_et.lk (Thilina Nuwan)]

Hello there, I am running on elastic search 5.3 and when i insert data to the document it creates a record with strange id and query in it as in below picture.

Please see my mapping below.

The way i used to insert data as below.

And Here is my search query..

My question is that why those strange record generate in my document and how to avoid that..?
