I Add another question
I insert "FA", "FB". Tree has this shape.
B
--------------> N3
F | A
root ----------> N1 -------------> N2
I search "F", Entry is
Cursor
- depth:1
- parent:root
- child:N1
- index:0
- length:1
Key:None
When lookup function evaluates,
child.header.length(1, "F") is equal to self.cursor.length(1, "F")
and try to return body.
What is wrong in this case?

- I cannot understand your first question. What are you asking for?
encode_key()
makes sure that a key should never be a prefix of another key. So insertingFA
and then looking upF
is impossible.

Oh, I don't recognize about encode_key()
First case is similar as second one. "FO" is prefix of "FOO", so don't happen.
Thanks
