Elastic Search nested multimatch query

Question

So my problem is basically the same as described here, however it still remains unanswered on the group.

My mapping:

{
    \"abstract\": {
        \"         


        

Answer 1

Changing your mapping to the following one which uses include_in_root: true will allow you to use the query you original wrote:

{
    "abstract": {
        "properties": {
            "summary": {
                "type": "string"
            }
        }
    },
    "authors": {
        "type": "nested",
        "include_in_root": true,
        "properties": {
            "first_name": {
                "type": "string"
            },
            "last_name": {
                 "type": "string"
            }
        }
    }
}

You may want to index inner objects both as nested fields and as flattened object fields. This can be achieved by setting include_in_parent to true. - Link

Note: include_in_root may be deprecated in future versions of elasticsearch in favor of copy_to.
