Faceted browsing literally means exploring by filtering available information. This is particularly useful in narrowing down your choices by selecting things you you want.

The seek extension for the open source email client Thunderbird does exactly that, it lets you zero down on emails that you are looking for by narrowing down your choices every time you make a selection.
