Some time ago, I've put up a number of search plugins for the Internet Search Applet. This might be helpful for some of you.
Also, don't forget tabletSearch for any tablet-relevant search.
This searches your Google notebooks and displays the results in the mobile version of the page (no junk, just the notes, in a top-down list). If you've not started using Google Notebook - start, it's an awesome tool (unless you've not yet sold your soul to Google and are still concerned about all that privacy stuff). The mobile page really works well with the N810. A Notebook is a great way to move stuff back and forth between the N810 and a desktop system.
Oh, and I ripped and cropped the Google Notebook icon right off the Google page in the N810. I cropped it to just "Notebook" for the search icon. Too easy
