Abstract
An example method of expanding a search is provided. In this example, a query used in the search is initially accessed. Other queries associated with the accessed query are identified, and these other queries include query terms. A diversity of the query terms is measured and the accessed query may be expanded with the query terms based on the measured diversity. Another example method is also provided for expanding a search. In this alternate example, a result set resulting from the search is accessed and a diversity of the result set is measured. The query used in the search may then be expanded based on this measured diversity.
