Abstract
A method and system for a search based on diversity is described. The system calculates a diversity index for a result set comprising results for a query. The diversity index is a measure of diversity among the results of the query. The diversity index relates to differences among the results. The system compares the diversity index to a threshold value. Finally, the system expands the query with one or more query terms based on the comparison.
