8. The method of claim 1 , wherein the updated set of results based on the selected one or more additional search queries comprises at least one result from the set of results for the first search query.

9. The method of claim 1 , wherein:

the first search query comprises a first textual search query that comprises a first set of words; and

the one or more additional search queries comprise one or more additional textual search queries, wherein each of the one or more additional textual search queries comprises at least one additional word not included in the first set of words.

10. The system of claim 2 , wherein the one or more computers are further configured to perform operations comprising:

ranking the identified one or more attributes;

wherein automatically generating the selectable list comprises automatically generating the one or more additional search queries based on the first search query, the at least one entity, the one or more attributes, and the ranking.

11. The system of claim 2 , wherein the ranking is based on frequency of occurrence.

12. The system of claim 2 , wherein the ranking is based on a location of each of the one or more attributes with respect to the entity reference in the set of results.

13. The system of claim 2 , wherein the one or more distinct entities comprise a plurality of distinct entities, and wherein the one or more computers are further configured to perform operations comprising, prior to automatically generating the selectable list of the one or more additional search queries:

providing the plurality of distinct entities for display within the user interface; and

receiving a selection of at least a first entity of the plurality of distinct entities;

wherein identifying the one or more attributes of the at least one entity comprises identifying one or more attributes of the selected first entity; and
