Use Tags to initiate Search

Posted: asked May 18 at 20:03 - Source : stackoverflow

first of all im new to Wordpress and PHP and i apologize if this is a basic question. I have a Wordpress installation and every post is marked with Tags and these Tags contain a link with:

href=domain.com/index.php/tag/TAGNAME

but i want the Link to be:

href=domain.com/index.php/search/TAGNAME

As far as i understand it i need to change the get_tag_link() but all is does is use the get_term_link() and then im totaly lost. Is there somewere a function which says If(tag){ return "/tag/"} which i can modify? The Theme i use uses this function for "breadcrumbs" http://dimox.net/wordpress-breadcrumbs-without-a-plugin/ but i dont know if this i relevant in any form.

Thank you very much.
