You want to find an anagram tool to find all the combinations for words. The two links below are of effective anagram solvers. Andy's will give you many more, but it will cut off its list at 400 of them so you don't see the end of the list. Its advantage is that you can limit how many words your solutions are and it has different languages. Wordsmith's will have fewer words anagrams, but the words will probably be more useful to you.
