we have an index and we use it to show documents which we retreive on a paged basis. i.e the query will be

```auto
{  
.From((page - 1) * pageSize)
      .Size(25)
      .Sort(sort => //etc
}

```

How can we figure out if we have document id, which page it falls on (Efficiently)?

I think we figured out a way of doing it and are testing.  
Thanks anyway.
