12. An electronic device, comprising: one or more processors; memory coupled to the one or more processors; a touch-sensitive display communicatively coupled to the one or more processors to render a content item and to detect user inputs of varying force; a content item stored in the memory; and a search refinement module, stored in the memory and executable on the one or more processors to: receive an indication that the touch-sensitive display has detected a user input selecting a term within the content item with an initial amount of force; cause display of initial search results associated with the selected term on the touch-sensitive display at least partly in response to the receiving of the indication associated with the user input; receive an indication that the touch-sensitive display has detected another user input having a greater or lesser amount of force than the initial amount of force; and refine the initial search results displayed on the touch-sensitive display to generate refined search results, the refining of the initial search results at least partly in response to the receiving of the indication associated with the another user input, the refined search results comprising at least a subset of the initial search results.

An electronic device as recited in claim 12 , wherein the receiving of the indication associated with the another user input comprises receiving an indication that the touch-sensitive display has detected the greater amount of force, and wherein the refining of the initial search results comprises narrowing the initial search results displayed on the touch-sensitive display.
