public class ExtractKeywordsReport
extends Report

ExtractKeywordsReport implements a report, which extracts keywords from the statistical query and result data. The algorithm works as follows:

• Get the n most popular queries for a given period.
• For each query, retrieve the results that were selected the most. Whether a result is considered relevant depends on the number of times it was selected. The threshold is set to half the value of the most selected result, but at least 2.
