Comparison Study for Search Engines

[John C. Matylonek]

I know this is a recent thread, but could someone recap the list
of references, studies, urls, that describe the searching 
algorithms, and features of the various web search engines?

What I'm particularily interested in is how companies utilize the
knowledge of searching algorithms to maximize the chances that
thier sites come up high on the list.
