I've got a wordpress site thats associated with laptops niche. And So I have multiple groups like Display(10inch, 13inch, 15inch...), Processor(AMD, Apple), Hard disk drive(120GB, 320GB, 500GB...) etc.

The typical search isn't good. I wish to create a professional search page where user can choose from options(drop downs/checkboxes) during these different felines and also the corresponding search engine results are displayed.

Any directions about this is great help (plug ins/styles/hacks).

This tut on adding search by category in WordPress should have the desired effect :)
