Abstract
In one implementation, a method is described for identifying candidate query refinements for a given query from past queries submitted by one or more users. The method includes generating from the candidate query refinements, term occurrence scores for terms in the candidate query refinements indicating frequency of the terms within the candidate query refinements. The method further includes calculating query refinement scores for the candidate query refinements of the given query using the term occurrence scores. The method further includes storing data associating the query refinement scores with the candidate query refinements for use in selecting from among the candidate query refinements for the given query.
