I want to sort some entities(A)，each of them is related to another kind of entity(B). Different A has different relation score with B。I want to query A by B and sort them by relation scores。  
some samples for A：

```
{
	"name":"aaa",
	"bEntitys":{
		"b_1": 1,
		"b_2": 3,
		"b_4": 5
	}
}
{
	"name":"ccc",
	"bEntitys":{
		"b_1": 1,
		"b_3": 3,
		"b_5": 5
	}
}
{
	"name":"eee",
	"bEntitys":{
		"b_2": 1,
		"b_3": 3,
		"b_4": 5,
		"b_5": 8,
		"b_6": 0,
		"b_7": 3
	}
}
{
	"name":"fff",
	"bEntitys":{
		"b_1": 1
	}
}

```

At present, I import the `bEntitys` field into ES with `Object` type and indexed them. so,I can search them with the logic of:(search b\_1,for example)

1. Filter: field `bEntitys.b_1` is exist.
2. Sort: get `bEntitys.b_1`'s score for sort.

Question is that, every key of `bEntitys` will be the field of the current index(json field will be paved). when there is a lot of B,it is going to exceed the maximum limit of index fields.

In addition, may be `script` can do this，but Its performance is not good.  
Is there any other ways?  
Thanks.
