Can anyone tell me if it's possible to call the Search.aspx page with a querystring so that the page loads with with a category, manufacturer and/or keyword already specified?

Or, if that's not possible, is there a way to easily create a search box that will search a specific category or manufacturer?

You can use a querystring like
search.aspx?k=headphone&c=65&m=129
c is the categoryid
m is the manufacturer id

Thanks Judy. I figured it was probably something simply. I appreciate the help.
