Elasticsearch映射中的显式数组类型

Question

Is there a way to explicitly specify that a property is expected to be an array in the mapping?

Here is the relevant part of my json schema to generate the mapping: myArray should be an array. This is implicit done if i put 'myArray' with more than one value into the index. But i want that 'myArray' is also handled as array (in the response) if there is only one or zero values. Otherwise my elasticsearch clients are confused with the mapping from json to c# objects (Newtonsoft.Json).

"myArray":{
    "properties":{
        "start":{
            "type":"date",
            "format":"dateOptionalTime"
        },
        "end":{
            "type":"date",
            "format":"dateOptionalTime"
        },
        "nr":{
            "type":"long"
        }
    }
}

In ES 1.x everything is treated as an array. I would suggest upgrading.
