Thanks :)

The example is fine.
With Java, you need to do the following : Add an H, change the J for an E, change the second A for an E and finally add a N.
That's 4 permutations compared to Python's 5 (Change P for J, change Y for E, change T for A, change H for V, change E for N).

EDIT : Typoes

In python, the find_most_similar function definition should take the parameters (self,term) instead of only (term).
