For example, if I have these 2 Documents:

```
id: 1
multifield: 2, 5

id: 2
multifield: 2, 5, 9

```

Then say I have a **set** that I'm querying with, which is {2, 5, 7}. What I would want is document 1 returned because 2 and 5 are both contained in the set. But document 2 should not be returned because 9 is not in the set.

Both the multivalued field and my set are of arbitrary length. Hopefully that makes sense.
