The Searching User feature allows you to show data to your users even if they do not have browsing permissions. When the Searching User is selected, users can see all the issues that the searching User is allowed to see.
For configuration, go to Manage Apps → STAGIL Assets → Lookup Panels. Select the panel to configure → Edit STAGIL Asset Lookup → Data Logic. Go to Searching User field and select the user, whose permissions need to define browsing permissions for other users.
This feature allows to define browsing permissions only for panels with display style Table or List.
