Please add the possibility to search by TAG and permission

A use case for permission:

• Identify all articles with unrestricted access and make them restricted
• Add a second group to a group of articles with a set permission
• identify all articles with a set permission and move them to a different manual/chapter

A use case for TAGS

• select all articles with a certain tag ad add a second one
• select all articles with a certain tag and set a permission
• select all articles with a certain TAG and move them

Not having this is severely limiting our ability to adapt the content we generate to a scenario that keeps changing due to business requirement and internal experimentation
