Does links not search for and display sub categories? Here is an example to illustrate what I am refering to.

I have a sub category named Ethernet 2 D under the main category, Cabletron. When I search for ethernet I only get a result of links(products) with the term ethernet in them, and not a listing of the category Cabletron/Ethernert in the category results. You can take a look here and try it out
http://24.147.131.6/products/index.html (this is running off my local machine so if you try getting this page and it doesn't come up, then I have shut down the server for some rest)

Anyone understand what I am trying to get to? Did i miss something?

Thanks,
Ian
