I have a list of location names at the root of a site collection. I have a site column at the site collection level that is a lookup to the locations list. In sub sites I use the site column in document libraries. I created a custom search page to return results across all the libraries and I want to add the list of places as a refiner. Unfortunately, the dropdown for refiner on the managed property is grayed out.
I did find this note at TechNet:
"By default, lookup columns are not automatically promoted to search refiners; manual steps requiring a high level of user rights must be completed to enable this"
Anyone know what the steps are?
Note that I am limited to Site Collection admin.
