I have a library with a Managed Metadata column titled 'Doc Keywords'. The library is searchable from a custom search page with a number of refiners, on of which refines on the Doc Keywords column. Some of the Keywords displayed in the search refiner do not return a complete result set.
The Data Protection Refiner Appears in the list
When selected, only 1 of the 2 documents in the target library is returned by search
What could be causing this behaviour?
