Advanced Web Search
Below is my advanced Google search. I am actually including two that I tried. It was interesting to learn about the shortcuts such as +, -, and [], but I also think that when I had to limit it to less than 20 examples, it was harder to find what I was actually looking for. Perhaps my topic was too broad, but I felt that about halfway through, even with hundreds or thousands of hits, the top ten were exactly what I wanted. In other words, I think the search engines (or the spiders) are already pretty smart.
