Right.

The problem with this line of thought is that the user will see
messages that he won't know what to do with.  There should be no
message on clog at all if the search succeeds down another branch.

One can use exceptions in this context just fine.  When you recurse,
you can catch the exceptions, only to throw a new (or a saved old) one
should the final search results come up empty.
