This is the response I got from google when I emailed them about the algo:
Thank you for your note. Google uses spell checking software to check queries against the most common spelling of each word. When we calculate a greater number of relevant search results with an alternative spelling, you'll see "Did you mean: (more common spelling)" at the top of your search results page.
For example, a search for [ Google bot ] returns approximately 1,620,000 search results. At the top of the search results page, you'll see "Did you mean: Googlebot." Clicking on "Googlebot," the correct spelling of our web crawler, yields a search with nearly a million more results.
Please note that our spell check feature is completely automated, and we cannot make manual changes to individual suggestions.

I still think this sucks. They should be able to add a function to there algo to ignore certain words. Thanks again google.
