This shows the results of a search given the criteria provided by the search facet sidebar. Within the sidebar, a traditional keyword search can be provided. This will search for objects that contain the given text.
You can then further filter the results using the remaining sections that describe different facets. You can filter by the type by switching off types you do not care about. For the other sections, environment and architecture and tags, you can switch on the ones you do care about. Objects that do not match the switched on items will not be within the list. If all switches are off for the environment and architecture and tags, then the results will contain all items and not be filtered.
