This is not really a Python problem - would be the same with any 
server-side techno...

You shouldn't use buttons for navigation, but links. The simplest 
solution is to pass all the relevant data into the query string (the 
?key=val&key2=val2&etc=etc part of the url). In your case, this would be 
something like resending all the search params, and adding the current 
page and the action (ie 'action=next' or 'action=first' etc...)
