I have a document library in SharePoint 2013 on premise. I have added a 'Document Type' site column of Choice type in the document library. Now I will add 'Document Type' as refiners in the search page.

My document library will have many records(more than 20k). So if I add 'Document Type' as index column in my document library then will it help as refiner in a search page or not.

Should I add 'Document Type' as index column to improve the performance as refiner or it will not help as refiner?


It should not affect the refiner since the refiner is working against the search index, not the list's index

  • Thank you for reply, so just to set column as index will not help in search as refiner. – SharepointDEV May 24 '17 at 6:29
  • No it should not impact the search refiner experience – Robert Lindgren May 24 '17 at 6:41
