There again, spelling is everything (one "r"), so M.Ted brings up a good point about doing a search on part of a word if you find yourself coming up empty-handed searching for the whole word (while unknowingly misspelling it). It might be a good idea to do searches on different sections of such a word ("Guan", "antan", "mera") to find more hits... such as, for example, that Mudcat thread I linked to above that was spelled "quantanamera". .
Note, too, that on Mudcat you can change the Subject line of your post to a thread. For this thread, I'm entering "Guantanamera" so that, in the future, others who do Forum Searches will find this thread. That's how I found the "quantanamera" thread: some kindly soul changed his Subject line to the correct spelling.
