17. A computer readable storage device storing a software program to cause a computing device to: determine a user context based on a tunable parameter; determine a first aspect of the user context and a second aspect of the user context, wherein the first aspect of the user context includes data indicative of text being accessed by a user and the second aspect of the user context includes data indicative of at least one user task from a plurality of user tasks, wherein the at least one user task is determined based upon the user context of the user's interaction with one or more software applications; formulate a first query and a second query based on the first aspect of the user context, the first query and the second query being different than the user context; submit the first query to a first search engine; receive a first plurality of search results from the first search engine, the first plurality of search results being based on the first query; submit the second query to a second different search engine; receive a second plurality of search results from the second different search engine, the second plurality of search results being based on the second query; determine a first plurality of scores associated with the first plurality of search results at least in part by comparing data indicative of the first plurality of search results to data indicative of the first aspect of the user context; determine a second plurality of scores associated with the second plurality of search results at least in part by comparing data indicative of the second plurality of search results to the data indicative of the first aspect of the user context; and display a subset of the plurality of search results on a client device, wherein at least one of the first plurality of search results is filtered from being displayed to the user based on at least a portion of the first plurality of scores, and wherein at least one of the second plurality of search results is filtered from being displayed to the user based on at least a portion of the second plurality of scores.
