Search Groups are used to group Search Groups and Searches together. The Search Groups can be organized in a multilevel tree structure, where a Search Group can contain other Search Groups. A Search Group can contain multiple Searches, which are used to list Tasks that meet the Search's criteria.
Search Groups are also used to run all the Searches that are in the Search Group simultaneously. The results of all the Search Group’s Searches are returned in a single window.
