Well, my webserver's upstream is being a PITA, and I was feeling especially perverse earlier today, so I ended up making a Javascript version of this concept. The advantage is that this is local to the n900, so you can still search Google even if these other services are down.

Nongeek HowTo:
1) Download the attached file to the Documents folder. (I believe this is the browser default)
2) Launch X-Terminal, and run the following (really basic) command: 3 Follow steps in post #1 by evad in this thread, except that in step 2 change the configuration value to: The same keywords from evad's search setup are in that file. Advanced users can add more keywords pretty easily - just open search.htm in any text editor and add more search URLs to the array. Getting the necessary URLs for said keywords is left as an exercise for the reader... unless you ask really really nicely.

Hope this helps!
