Search Input Rules
 

Very basic question :
What are the rules?
What to input, or not to, in the search window?
I mean: "*" "." "*.*" "Mysearch.*"
"My search.*" M??.btw" "Mysearch txt"
and so on...
Can you make it clear to everyone ?
I tried to learn from gnutella site, but they makes a bug/mistake in their explanation, and as a result it's not quite clear/understandable.
Beside, I would like to encourage your impressive works, and say BRAVO and THANK YOU for what you bring to everybody.

Wildcards haven’t been implemented yet and file extensions are unnecessary.
