Clustering Query Results

Ferret supports drilling into the results of a query to understand underlying structure through clustering on the different attributes of the results.

For example: the references to a method, which are generally themselves methods, may be clustered into different groups identified by attributes such as their access protection (public, private, package, or default), their containing type, their package, or boolean attributes such as static vs. non-static. Some clusterings may have results belong to multiple groups, such as might arise for a clustering by argument types: the method Arrays.addList(Collection, Object[]) would added to groups for Collection and Object.
