Serializing query _source without includes or excludes fails

[Romanx]

Both of the following examples are equivalent in terms of ES however the second is the only one that works when serializing a query into a SearchResponse.

  "_source": [
      "id",
      "price",
      "tradeprice",
      "title",
      "description",
      "url",
      "abv",
      "volume",
      "age",
      "stocklevel",
      "hasdram",
      "productimage",
      "atomstock",
      "distilleryurl",
      "isdiscontinued",
      "comingsoon",
      "stockincoming",
      "distillery",
      "releasedate",
      "isvatableproduct",
      "hasfreeshipping",
      "userrating",
      "preorder",
      "maxnumberpercustomer",
      "reviewcount"
    ],

  "_source": {
    "include": [
      "id",
      "price",
      "tradeprice",
      "title",
      "description",
      "url",
      "abv",
      "volume",
      "age",
      "stocklevel",
      "hasdram",
      "productimage",
      "atomstock",
      "distilleryurl",
      "isdiscontinued",
      "comingsoon",
      "stockincoming",
      "distillery",
      "releasedate",
      "isvatableproduct",
      "hasfreeshipping",
      "userrating",
      "preorder",
      "maxnumberpercustomer",
      "reviewcount"
    ]
  }

hey @Romanx, The source filter in NEST only supports the form

"_source": {
    "include": [ "field1", "field2" ],
    "exclude": [ "field3" ]
}

hey @russcam, I spotted that an updated my query, wasn't sure if you wanted to provide a route to serialize "_source": [] approach into "_source": { "include": [] } as ES allows both.

If not feel free to close this 😄

@russcam 👍 thanks, I think it'll solve some confusing problems for people wondering why their queries that work in ES won't serialize.
