Google search algorithm
We all know Lucene algorithm (thanks to open source:).
Anybody has a general idea of how Google search
algorithm works? How is the page ranking (I don't mean
the paid ones) determined by Google? I have strong
interest to know this. Any idea or feedback will be
appreciated. Thanks!
Ardor

I read somewhere that it used a hidden markov model.
It checks each page and gives each link a click probability.
It also gives a probability that the user will enter a new
address instead of clicking a link.
We then, by using a hidden markov model, calculate the
probability that the user will be at a particular page
after an infinite time using random browsing according
to the probabilies found.
This probability is then used as a basis for ranking
results.

This is not quite related to Lucene but I found a web page that
has quite a few links about this subject:
http://www.google.com/search?q=google+page+rank&sourceid=mozilla-search&start=0&start=0&ie=utf-8&oe=utf-8
:-).
