Why not expose the various possibilities through different names?

# nearest k points (possibly fewer)
query_nearest(pt, k=1)

# all points within given distance
query_sphere(pt, distance)

#nearest k points within given distance (possibly fewer)
query(pt, k, distance)

Few people will use the last form, but it's useful nevertheless.
