A new type of search

When I'm stuck on the command line, trying to figure out regular expressions, or the correct syntax for a command I do the follow

1. Search Google
2. Select Page
3. Qualify Page is what I want and then bookmark using del.icio.us. The tags I use tend to be the same as search terms

What frequently happens, maybe days, maybe weeks later I'm doing the same thing. I repeat the process as its quicker than the 2 steps of seeing if I have something bookmarked already, and then searching.

The net effect is the value I obtain from del.icio.us is not as great as it could be. What I would like is a custom search indexes my del.icio.us links, then I could:

1. Search using my custom search
2. If any of my del.icio.us links match the terms in tags or content they appear first
3. Content from the web appears second

The benefit of this would be that pre qualified pages bookmarked previously would be a higher ranking. I suppose its a personal page ranking system.
