My b2evolution Version: 1.10.x

Is there a way in the code that i can change the core files to link the tags requested to a search query page? Here is an example of what i would like to happen:

original Url (how B2 is constructed now)
http://site.com/stupid;

i would like it to look as if it were searched like this:
http://site.com/?s=stupid&sentence=AND&submit=Search

Basically i would like it so that it no longer appends the ";" for search engine frendliness and instead tags no longer use the "stupid;" format but a more reliable and logical "?s=stupid&sentence=AND&submit=Search"

Is there a way to do this from the core of B2 i know it seems simple but i'm a ilttle bit of a newbie to this and i don't want to have to change it via htaccess it just seems too complicated and it might mess up all the other lovely little things that i have going on right now. Please help and i appreciate any advice that you can give

Thanks
