The Global Search bar works in two methods: text or page code. Page code searching goes against Application Page Registration data. The text searching method goes against the currently selected business role by default. Entering text starts a search against the business activities and system resource targets not only by name, but also by description.
By default, all types of system resource targets are searched with an option to filter results down to just those of a particular type.
The magnifying glass icon opens up the following panel that can be used to adjust a text search. Adjustments include selecting one or more roles to search simultaneously, as well as selecting All Roles. Within a role, a search can be narrowed down to one or more business activities. The results appear beneath the Advanced Search section.
