Advanced search can do what you want. A good example is to look at the ez site, at:
http://ez.no/content/advancedsearch
Look at the source and it will show you what hidden variables you need to set. Basically you need to tell the advancedsearch how you want to search by means of hidden variables.
Thanks, but it isn't exactly what I am looking for. The http://ez.no advanced search gets its parameters through an HTTP POST, not a GET.
I don't want to use a form since it is not consistent with the look & feel of my site. I would far prefer to have a set of <a href=...></a> links in a floating <div>. I posted another message about passing parameters using an HTTP GET, but no response yet. I am going to assume for the moment that it cannot be done :(
