This is something that can be easily done with Job's tool, at least for exact matches, just one needs a bit of patience to add 28 (non-unique) stars into the rendering.
I just did the same for six You are not allowed to view links. Register or Login to view. labels (actually, only four of them are not unique), and there are no adjacent occurrences (for exact matches).
