I noticed that if I once a while browse through a Facebook page of a person, with whom I have no mutual interests/friends/2nd-tier-friends/region, Facebook Search ranks this person's page higher then my friends in the search suggestions.
When I download "all data about me" from Facebook's settings, that person is not listed there.
Does this mean, that the data that Facebook provides for download is not full? Then what is the purpose of it? Is it defined somewhere that this data should be full?
