Does anyone have any information on customising Sharepoint Portal searching?

I am trying to get list contents included in the portal search and am struggling. Have removed and amended the included / excluded content in 'Configure Search and Indexing' to basically include everything and have added *.aspx as suggested on a blog I found, but this still doesn't seem to be working.

If it makes a difference, the list in question is on the sub-site of a site from the portal, so the third level down if you like.
