Actually it doesn't matter that the title has S not R in it. Google finds it
either way (or at least it did for me). It could be that at the moment the
Frank Schwach's search was executed the now rather arbitrary relevance
ranking scheme placed the desired document out of limits.

It is also possible that the timeslice on the Google server expired before
their retrieval agent found the required document. This "feature" of Google
isn't widely known but is the reason why one should do a Google search more
than once or even at different times of the day to circumvent time-slicing.
I suspect if we use R to calculate the conventional relevance and recall
metrics for Google that the results would be much lower than expected.
