I'm using SharePoint 2013 Enterprise on-premises.
So I've scoured the Search Schema up and down. I've perused & searched everyone of the Managed Properties and Crawled Properties. I simply cannot find one for a specific site column. The display name of the site column is 'Department'; however, when I click to edit the column, the url query string says Field=Division. I've searched managed & crawled properties for Division and found nothing. I've used the search api with the following URL:
http://<sharepoint 2013 server>/_api/search/query?querytext='"Tutorials"'&selectproperties='RankingWeightHigh,Department,People:Department,DiscussionCategory,ows_Category,Rank,Title,Path,FileExtension,ContentTypeId,IsDocument'
Department shows in the xml results that display, but it's Null. I'm wondering if this property doesn't refer to the Department field on the user profile..??
I've performed a full crawl, just in case, but the value for Department is still null. The 2 managed properties we have associated with Department are People:Department and ows_Department. The Department field is queryable, searchable, retreiveable, and refinable (with 'Yes-Active' as the value).
Does anyone have any thoughts at all on what else I can try or what settings I should check?
