ElasticSearch: Return the query within the response body when hits = 0 - elasticsearch

Question

Please note that the following example is a very minified version of a real life use case, it is for the question to be easy to read and to make a point.
I have the following document structure:
{
"date" : 1400500,
"idc" : 1001,
"name": "somebody",
}
I am performing an _msearch query (multiple searchs at a time) based on different values (the "idc" and a "date" range)
When ES could not find any documents for the given date range it returns:
"hits":{
"total":0,
"max_score":null,
"hits":[
]
}
But, since there are N results, I cannot tell which "idc" and what "date" range was this result for.
I would like the response to have the "searched" date range and "idc" when there are no results for the given query. for example, if I am searching documents for IDC = 1001 and date between 1400100 and 1400200, but there are no results found, the response should have the query terms in the response body, something like this:
"hits":{
"total":0,
"max_score":null,
"query": {
"date": {
"gt": 1400100,
"lte": 1400200,
}
"idc": 1001,
}
}
That way I can tell what date range and "idc" combination has no results.

This is from the docs
multi search API(_msearch) response returns a responses array, which includes the search
response and status code for each search request matching its order in
the original multi search request.
since you know the order in which you sent the requests , you can find out which request failed.
