@aclassen Those documents were in a public space for a prospect of ours, and that content has been deleted since then. For an unknown reason currently under investigation, this deletion did not entirely work on the search index reason why it temporarily appeared in your search results.
As a side note, for profile search, it shows profiles for which you share a space/sub-space in common, which is the case for "Sylvain Jeandroz" (you both belong to EMCDDA)
Best,
