Inconsistent response of sort as a result of indexing of a predicate

@ahsan

 {
        "name": "bob",
        "class": "2"
      },
      {
        "name": "alice",
        "class": "5"
      },
      {
        "name": "cat"
      },
      {
        "name": "deg"
      }
    ]

This response is not correct by total ordering. "cat" and "deg" should not be in the result set.

@ahsan

"data": [
      {
        "name": "bob",
        "class": "2"
      },
      {
        "name": "alice",
        "class": "5"
      }
    ]

This response is correct by total ordering.
