Methods and systems for providing a response to a query. Multiple users'
search engine activity in regard to a query is correlated. A response is
provided based upon this correlated search engine activity information.
For one embodiment of the invention, in the context of search engine
result optimization, the user activity and/or user information of
multiple users, during a search session, is correlated with queries to
effect an evolving association between queries and the organization and
presentation of documents. Systems in accordance with such embodiments
employ the ability to store users' activity over the entire search
session, thus making possible the correlation of a number of different
types of user activity and user information. The use of correlated user
input allows such systems to provide relevant search results without the
limitations imposed by the key-word-based systems of the prior art.
