This behavior is the reason why I think certain single-word titles are poor choices; there's nothing wrong with one-word titles per se.

I agree with the first and the last part of the above statement - I disagree with the conclusion in the middle. It's the behavior that causes the problem - the one-word title is merely the trigger. So, fix the behavior. Searching with a single keyword is common. So, if it's a problem that a search with a single keyword jumps directly to a page instead of showing a list of alternatives - don't jump. Show the list!
This reminds me about the story of the man who went to the doctor saying his eye hurts when drinking tea. And instead of suggesting to take out the spoon, the doctor tells the patient to stop taking sugar in his tea.
