     `kFRSearch(q, sqRad, k, eps)`
         Fixed radius search. Find at most `k` nearest neighbors of the query point
-        `q` within radius `sqRad`, with an allowed error of `eps`.
+        `q` within radius `sqRad`, with an allowed error of `eps`. Returns
+        `(idx,dists,k)`; the first two are the same as above, and the last is
