How to update parentlocation in XSLT?

Question

Hi!

I am using google search appliance for search. When I run a search term say "text1" it displays the result in the iframe.

Then on the second time when i do a search say "text2" and click on one of the links from the result and return back using the back button, after visitng page. It show the search term "text1" instead of the search term "text2".

how do I make this display the latest search term instead of the very 1st search term?

Thanks
