We ( http://www.plexisearch.com http://www.plexisearch.com ) expose our secrets. We'll show you what page flags are changing the rankings. We don't share quite everything, mostly because some features are beta and we don't want to look too stupid when we get something wrong... But about 90% of the indicators we used to determine the rankings are exposed. The formula changes based on the type of search, and the type of results we found, but the indicators are all exposed.
