I am facing this weird issue inside our sharepoint online tenant:-

  1. I have a classic team site collection, which contain 2 docuemnt libraries inside 2 separate sub-sites.
  2. the document libraries are using the defualt content type.
  3. now i wanted to add indexes for these document libraries (So i went to the document library settings >> Indexes >> Create), but i have noted that the indexes' options inside these 2 document libraries are different, as follow:-

    • inside the first document library i got these indexes:- enter image description here

    • while on the second document library i got these indexes (where indexes such as MediaServiceAutoTags & MediaServiceLocation are missing):- enter image description here

so can anyone advice why i got these differences? although the 2 document libraries have the same structure...

and second question which is less important, what do these 2 indexes MediaServiceAutoTags & MediaServiceLocation represent and how we can populate their values inside the documents ?

1 Answer 1


The fields MediaService*** are related to Image Analysis functionality. SharePoint o365 automatically analyse the image and update these columns example the location MediaServiceLocation. They are metadata columns related to an image.

  • ok thanks for the info, but why i am getting these inside one document library only?
