Looking for search plugin with options

Hi.
Iam looking for search plugin with selectable options.I have website about webhosting offers and i want to make it easier for my visitors to choose wich kind of webhosting they are looking for!

So instead of writing webhosting in search box,they can choose linux or windows option and how much the diskspace they need and many more options..

Please if anybody has an idea about such plugin let me know

Thanks
