Removing the built-in Search

[medicalforums]

Now that I added Google Search to my vb site
I want to get rid of the built-in vb search

First ) Is there any option to disable so that it doesn't show

Second) If there isn't such an option , what code should I delete from the navbar template so that it won't show

Third) After removing the link in the navbar, is there a need to disable the search indexing so as not to load the server with unnecessary load, if needed how do I do that?

Sorry that should have been three threads!
