Advance Search filters as Drop Down with Home Page Search?

Search Box on top of Home Page, I'd like to allow users to filter their search before they begin if they want.



Yes, most would just enter the item they seek. But some want to search for an item within a specific price range. (I have attached some examples) [attachment=7163:advancedsearch.jpg]



I'd like to see a down arrow or filter icon or “advanced” hyperlink to open a filter by price prior to submitting the search.



Any suggestions would be greatly appreciated.
