How to search by nested in elasticsearch?

Question

MongoDB

there are Users they have an array of eDates:

"eDates" : [ 
        {
            "dateFrom" : ISODate("2017-04-01T12:33:50.000+0000"), 
            "dateTo" : ISODate("2017-04-05T12:33:50.000+0000"), 
            "_id" : ObjectId("58c2ab50875060766968d41d")
        }, 
        {
            "dateFrom" : ISODate("2017-10-01T12:34:04.000+0000"), 
            "dateTo" : ISODate("2017-10-07T12:34:04.000+0000"), 
            "_id" : ObjectId("58c2ab50875060766968d41c")
        }, ...
    ],

I need to filter by date users in which at least 1 element from the array matches the specified filter.
Those. i fill dateFrom and dateTo and search

let nested = []
let from = {"range" : {"eDates.dateFrom" : {"gt": new Date(data.dateFrom)} }};
let to = {"range" : {"eDates.dateTo" : {"lt": new Date(data.dateTo)} }};
nested.push(from, to);

"filter": {
"nested" : {
            "path" : "eDates",
            "query" : {
                "bool" : {
                    "must" : nested
                }
            }
        }
}

The problem is that it can find matches in different subs. objects and not exactly 1.
Similar to how it does it in mongo:
{ "eDates": { $elemMatch: {dateFrom: {$gte: ISODate("2016-04-04T00:00:00.000Z") }, dateTo: {$lte: ISODate("2017-04-27T00:00:00.000Z")} } } }

The problem is that in the usual order, an array of objects is mapped into one object when indexed.
That's why he finds it.
What would be looking for as you want - you need to change the mapping.
