What I’m calling Search 2.0 are actually third generation search technologies. To explain the generations:

* First-generation search ranked sites based on page content – examples are early yahoo.com and Alta Vista.
* Second-generation relies on link analysis for ranking – so they take the structure of the Web into account. Examples are Google and Overture.
* Third-generation search technologies are designed to combine the scalability of existing internet search engines with new and improved relevancy models; they bring into the equation user preferences, collaboration, collective intelligence, a rich user experience, and many other specialized capabilities that make information more productive.
