I just finished the excellent CS101 course at Udacity, which promised I'd learn to build a search engine in seven weeks. I was skeptical, but sure enough, I did! This very simple search engine is based on the code I learned in class, and searches the Udacity course materials. While building it, I also learned to use the Bottle web framework and Google App Engine. I kept a blog with lots of details here. The next round of classes starts tomorrow, so I thought I'd post this here and encourage anyone interested in learning to build their own to sign up.
