Controls if any internal extra searches should be removed or not.
Can be set in: profile.cfg, collection.cfg
This option can be used to stop the modern UI from removing internal extra searches it may create (e.g. facted navigation extra searches) from the main search’s search transaction. These internal extra searches are removed because it can make the search transaction large. It is sometimes useful to be able to view these internal searches for debugging.
By default internal extra searches are removed.
