Hi @Mohit_Rajput,

What do you mean by multiple document id? Each document indexed by elastic is given just [one id](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-id-field.html). Of course you can have multiple fields that hold unique values that could identify the document that you provide yourself but those are separate from the \_id value used by elastic.

What is your use case? As you can see in the documentation provided above you CAN specify the \_id value at index time which might be the solution you are looking for.
