I often can't remember the name of a Drupal module I want to download and use. For example, I can never remember if I need to go to drupal.org/projects/google-analytics or google_analytics or ganalytics or whatever. I am also not satisfied with the search provided on drupal.org. So I figured out a way to put together a Search Engine in Google Chrome to do an "I'm Feeling Lucky" search on site:drupal.org/project. Here is the search string I used:
https://www.google.com/search?q=site:drupal.org%2Fproject+%s&btnI&sourceid=navclient
The query parameter btnI sepcifies you want to do an "I'm Feeling Lucky" search that will automatically take you to the first result. So, in this case I just type "dp google analytics" in my URL bar and it takes me directly to what I want http://drupal.org/project/google_analytics. I'm sure this is useful in other places as well; such as searching the Drupal API documentation or replacing the search for any site that doesn't provide a decent search for itself.
