Inherit (Sticky) Fields are index fields that retain their values.
Each file/folder can inherit index fields values from its parent folder. To designate a field as a inherit field, mark the adjacent checkbox while creating a Profile.
For example, In-case you have the Client Name field under profile Project as an inherit field, the next time when you add a document and choose Project as profile, the Client Name field will inherit the value from its parent folder.
Note: The index fields will Inherit values from parent folders when you manually import documents into Docsvault using the 'Import files and folders' dialog.
