Ah, you want a different radius on each of the possible results points? I guess the radius is a property of the point node (or attribute of the geometry/feature). In this case I agree it's not the same. If all radii were the same, then it would be equivalent. In this case, however, I can think of one reasonable approximation. If you know the largest radius, and it is not too large, search the normal way for the largest distance, and do a second filter on the radius of the resulting points to remove those with smaller radii that don't overlap the search point. This could be done with dynamic layers, using CQL, or with GeoPipeline using a custom filter.
