There is no "fixing the Search function". It works fine. What needs to happen is for there to be only ONE search function for the board, and that's the one at the top right of every sub-section. The big one at the top of the main forum has never, and will never work, because this software package is designed that way.
As well, people need to take advantage of the whole "free education" system and learn to spell. That helps a great deal when searching for a thread title, because no matter how many times you put it in the box correctly, you'll never find "tell me about pedal's for amp's" or "help choosing pickup's for my Les Paul".
To understand the idiot, you must think like an idiot.
