From what I remember of the relevancy they had multiple machines each serving a different set of results.
The the machines with the best results for your keyword went down the front end just displayed what it had - which often was unrelated stuff from all the other machines that did reply.
Or in other words the lack of relevancy was due to the overload, not in principle due to their search algorithms.
