1. A computer-implemented method for using a human computation game to improve search engine performance, the computer-implemented method comprising performing computer-implemented operations for: displaying a page to two or more players via a multi-player game; upon displaying the page, receiving first terms from a first player and receiving second terms from a second player, causing a search engine to return first candidate pages in response to performing a first query using the first terms, causing the search engine to return second candidate pages in response to performing a second query using the second terms, assigning points to the first player if the first candidate pages returned by the search engine include the page displayed before the second candidate pages returned by the search engine include the page displayed, and assigning the points to the second player if the second candidate pages returned by the search engine include the page displayed before the first candidate pages returned by the search engine include the page displayed; storing one or more of the first terms and the second terms provided by the two or more players during play of the multi-player game and associated data; and utilizing the one or more of the first terms and the second terms and the associated data to improve results returned by the search engine.
7. The computer-implemented method of claim 1 , wherein utilizing the one or more of the first terms and the second terms to improve results returned by the search engine comprises performing a cognitive analysis on the one or more of the first terms and the second terms to identify searching behavior.
