Elastic Search search related

Let's say we have the following 3 documents stored in an ES Type:

Document 1:

{
  foo: [
    "c"
  ],
  bar: "bar1"
}

Document 2:

{
  foo: [
    "a"
    "b"
  ],
  bar: "bar2"
}

Document 3:

{
  foo: [
    "a",
    "b",
    "c"
  ],
  bar: "bar3"
}

I want to do a search in ES such that given the input foo: ['a', 'b', 'c', 'd'], the result should return only Document 3. This is basically saying, find that single document which has the max number of entries in the foo array.

You can use should and size is 1 so ideally the document 3 got high relevance and should be in the top. and size 1 will return the most relevant document 

"size" : 1,
"query": {
    "bool": {
      "should": [
        { "term": {"foo": "a"}},
        { "term": {"foo": "b"}},
        { "term": {"foo": "c"}},
        { "term": {"foo": "d"}},
      ]
}
