Here's a link to research on designing a search engine for chemistry which won't return as many irrelevant results. The algorithm was designed in the Penn State College of Information Sciences and Technology. "With the new engine, scientists searching for research on CH4 or methane no longer have to wade through search results about Channel 4 or Chapter 4 as ChemxSeer will only return documents with references to the chemical formula."
This seems to be an important achievement in search engines, because one common problem with search engines, such as Google, is unusually large search return sets. The other problem is a null set, when you think some information should be available. I had some trouble with the latter when I was searching for links to my Thoreau fragment, and had to think of some more creative ways to search.
