US Patent 7707220 Methods and apparatus for interactive searching techniques

Methods and systems for searching comprise presenting a first information set to a user, receiving feedback, applying an evolutionary algorithm based on the feedback to generate a search query, causing the search query to be executed to generate a second information set, and presenting the second information set to the user. Then, in response to user input, the first information set is again presented to the user; feedback is again received, an evolutionary algorithm is again applied based on the feedback to generate a search query, and the new search query is caused to be executed to generate a third information set which is presented to the user.
