14. The method of claim 1 , further comprising receiving an input from the user, wherein scoring the first set of content objects of the plurality of content objects is further based on the received input from the user, and wherein the plurality of structured queries are generated in response to the received input from the user.

15. The method of claim 14 , wherein the input from the user is an unstructured text query inputted by the user.

16. The method of claim 1 , wherein the plurality of structured queries are pre-generated rather than generated in response to an action from the user.
