Adsense for Small Business Using Google Custom Search – this 2008 announcement video from “Inside Adsense” mentions that Google Custom Search has enabled filtering to allow better results based on the topic of your site and lets you tune the results to your own site. The thing that isn’t mentioned in the video is that Google is phasing out the old version of Adsense for Search which means you had better update or you’ll lose the option to make money from ads in your own site search.
