Hi all,  
I have a document with the id `abc` and the requirement that when user search by `ab`, it should return my document.  
Currently, after I check Elasticsearch to see how appsearch indexes the document. I recoginize that the id field is diffrent from other fields, it's just stored as keyword.

```auto
"id": {
    "type": "keyword"
},

```

It means that when we want to search by id, we have to put an exact id (`abc` in my case), we could not search by `ab` or something similar.  
So I'm thinking that I will store another field having the same value of the id field (because the id is generated by the app) to fulfill the requirement.  
However, I wonder if we have another simpler solution for it?

Thanks in advance.

This is what I would suggest.
