Claim:
A method comprising: receiving a query that includes one or more terms, the query being associated with first resource identifiers, and the first resource identifiers being associated with first click-through data and ranking scores; identifying a similar query including a set of terms different from the one or more terms, the similar query being associated with second resource identifiers and the second resource identifiers being associated with second click-through data; determining a query similarity score between the query and the similar query, the query similarity score being based at least in part on a correlation between the first click-through data and the second click-through data; identifying a resource identifier of the second resource identifiers that is not included in the first resource identifiers; determining a ranking score between the resource identifier and the similar query; determining a combined ranking score associated with the resource identifier based on the ranking score and the query similarity score; and combining the resource identifier with the first resource identifiers to generate a set of query results, the set of query results being ranked based at least in part on the combined ranking score associated with the resource identifier and the ranking scores associated with the first resource identifiers.
