for some unknown reason I cannot find anymore anything when I do a search in document library at Sharepoint Online. There is also one other user who cannot find anything. This is what happens.
When library is opened, all the documents are well visible with metadata.
If I do a search with metadata (like always previously) the search tells me "We couldn't find any results for *"
What is this? Yesterday I had no problem. Like I said there is one user + me that has this problem. All of the others can make a search with correct result.
Your help is utterly needed.
