weird answer

[tibloop]

hello, i am trying out this application to achieve autocompletion. But it gives me weird results
Here is my entry :

25 hey
21 how do you do?
15 how I met your mother
10 hello world
9 great Days ahead

and my query : http://localhost:6767/face/suggest/?q=h&n=3

and the result :

"[ { "phrase": "hey", "score": 25 },
{ "phrase": "how do you do?", "score": 21 },
{ "phrase": "hello world", "score": 10 }]

Why is it not, hey/ how do you do / how i met, which are the most frequent ones??
thank you
