Organizing Search Results, Filters
Giving users a way to organize the results improves the user experience, it will be easier for customers to find the products they are looking for. Specially if your website is providing a long list of results, you have to give the possibility of sorting and filter them.

Download.com has a very good search results filter design. Results can be filtered by operation system, type of license, categories and more. Even better, from the usability point of view, is the fact that results can be sorted as the user clicks on name, date added and other columns.
