I have a calculated site column AlertSortOrder, which I added to a list. I created a managed property nvAlertSortOrder (sortable, searchable, queryable, retrievable) mapped to the corresponding crawled property (ows_AlertSortOrder). The problem - I am unable to filter/sort by that managed property, and when I check the raw search results using search api:
/searchcenter/_api/search/query?querytext='my unique list item title'&selectproperties=nvAlertSortOrder
that property is null.
