Systems and methods for collaborative searching are described. In an embodiment of the present invention, a database stores previously executed queries and corresponding results. An application server compares an entered query with the previously executed queries. If the application server finds a query that is substantially similar to the entered query, the application server returns the results corresponding to the previously executed query. If no substantially similar result is found, the query is executed against one or more data sources. When results are returned, an embodiment provides the user with the ability to rate them. The ratings are used to determine the similarity of various queries.
