searchid in search results url

[NeXuM]

Hello

Is it possible to remove the searchid from the search results url?
let me explain...

my search url looks like this:
http://www.pirate-punk.net/search.php?searchid=150393

but i want normal url like this:
http://www.pirate-punk.net/recherche...ss&forumchoice[]=54&forumchoice[]=53&forumchoice[]=62&forumchoice[]=65&showposts=0&query=b?rurier+noir

i dont like the short url with "searchid" because google bots will get a 301 redirect page when accessing a normal search url

i tryed to turn off 1 hour caching of the search results in my adminCP but it didn't help..
