How to implement the Fibonacci search algorithm?

Question

Algorithms

Good time of the day. I rummaged through the Internet a lot and did not quite understand one thing.
Searching with Fibonacci is how? I made a very simple program and at first I thought that this was the very search .. But I began to doubt and got confused at the end.
The program itself is simple and works, but in essence it is just a Fibonacci number..
Then how to make a search algorithm using the Fibonacci algorithm?

For clarity, I even attached a screen :)


And this is for those who find it difficult to understand my question. This is a task that I cannot complete. By the way, I do not ask you to complete the tasks, but I would only like to know what kind of search algorithms that I cannot do, and there is no example on the Internet. If anyone can help me with this, I'd be extremely grateful!

Develop a software module for demonstrating the comparison of the work of search algorithms using the Fibonacci algorithm and the bore algorithm.

Thanks for your time on this topic!
