Tough. You could still use the words table with cWord $ words.word, provided the cWord is long enough - or else you'd get too many false hits. It wouldn't make too much sense to search for HP inside words - who knows how many German compound words you may find that you don't need - but I figure anything with at least five characters is worth looking for inside the words.
