Checkbox left hand navigation drill down

Question

Does anyone have an idea on how I can go about creating this navigation? I have a section of a website that has subwords of a top vocabulary word that I would like to show in a left hand menu in order to drill down to the content with checkboxes.

[]Topic 1 ---> if checked show excerpts of all articles with this topic in the content area.
[]Topic 2 ---> if checked show these articles...
[]etc...

The user could check 1 or all of the topics and get the articles.

Thanks for any direction, help or the like!

Just to help others out here! This is called Faceted Search. After looking around and around online, I found it. There are a lot of posts about it. Drupal 7 uses Facet API to do this. However, it is still not extremely straight fwd...
