Search across "Shared with me" ?

ok, it seems that it took a while until the files (shared with me) were indexed. I can see them now.

another question , related to onedrive search:

is this really true that i can search for files (within onedrive) which follows one of thefollowing criteria ?

• Items in your OneDrive for Business.

• Items that someone has shared with you.

• Items that are stored on a site that you follow.

especially the last item is an interesting one:

example: if i'm member of 10 SPO sites, but i do not follow any of them, how can if find files then ?

so there is no global search across all sites where i'm member of (incl. my own onedrive), correct ?

If yes, why this is not possible and how you explain this to endusers ?

I'm just curious :)
