DataSearch and customQuery not working

[aihrig]

I'm trying to get a custom query working with the DataSearch component, but it doesn't seem to affect the actual request being made. The reason I'm doing this is that I need to call the "multi_search" endpoint on an enterprise ElasticSearch instance, and not the "_msearch" endpoint (I have the correct endpoint call working).

ElasticSearch doc: multi-search

The generated query is apparently invalid for the multi_search endpoint:

{"preference":"oem-part-id"}
{"query":{"bool":{"must":[{"bool":{"must":{"bool":{"should":[{"multi_match":{"query":"b","fields":["msg"],"type":"best_fields","operator":"or","fuzziness":0}},{"multi_match":{"query":"b","fields":["msg"],"type":"phrase","operator":"or"}},{"multi_match":{"query":"b","fields":["msg"],"type":"phrase_prefix","operator":"or"}}],"minimum_should_match":"1"}}}}]}},"size":10,"_source":{"includes":["*"],"excludes":[]}}

And I need the query to look like this (which works fine in postman):

{
    "queries": [
        {
            "query": "foo"
        }
    ]
}

My DataSearch component is:

            <DataSearch
                componentId="oem-part-id"
                dataField={['msg']}
                placeholder="Search OEM Part ID"
                className="custom-class"
                customQuery={props => ({
                    query: {
                        term: { "msg": "foo" }
                    }
                })}
             />
