I have a form that when posted sends the following to the querystring by default:

Code:
http://www.mysite.com/search.php?searchedfor=hello&submit=Search
There are also additional parameters called 'level' and 'duration' e.g.

Code:
http://www.mysite.com/search.php?level[]=1&duration[]=10&searchedfor=hello&submit=Search
Is it possible to have tidy urls with the above?

Perhaps something like:

Code:
http://www.mysite.com/search/level/1/duration/10
The added complication is both level and duration are arrays (from a checkbox) so could contain more than one value.
