Using the search function

no, but for your example I would do "bluebonnet tobus site:xmarksthescot.com"

It won't do exactly what you're looking for, but would give all threads that include bluebonnet and your username. This will obviously turn up more than what you're looking for, but also more than the zero you're currently getting

Obviously not the solution you're seeking, but perhaps a manageable workaround in the meantime.

That did the trick, thanks!

I'd still like to know how to do it using the forum's own software, though.
