Elasticsearch子映射

Question

I haven't not been able to find the answer to this question anywhere, so I'll try my luck here.

I know that I can map fields to a specific type in ES and that works well.

But say I have an data set:

{
    "main":{
        "field1": "test",
        "field2": 1,
        .
        .
        .
    }
}

Where the fields in main are arbitrary and change per document. What I cant seem to find is if there is a way to map all fields no matter what type they are inside main, to text. I can get it work if i explicitly map every fields, but the fields change and can be added at any time, so I can not possibly map them all.

Dynamic template can be used to map fields dynamically added to specific mapping. Please refer to this documentation .
