In Google Drive I was searching for a document of mine, when all of a sudden one of the hits was a spreadsheet called "FCRJ". I had no idea what it was, so I took a look and it's a document made by someone else with seemingly gibberish that has been added to and modified since 2009. The history of the document is an absolute mystery of randomness too. I would almost suspect it is random bits of notes automatically harvested from various sources.
The author is "anonymous" and the location according to Google Drive is "-".
Why do I have access to this document all of a sudden? It does not sit in any shared folder, it contains bits and pieces of medical research, education reports, electrical current table, etc. Seemingly without any order or meaning. And I have access to it ... ?
Is there a concept of publically searchable documents in Google Drive that I have been unaware of? Until now, I have been under the impression that the search is restricted to your own documents.
edit: New information on the owner: I have some new information that might shed some light on this mystery. Although the Document details, available from the file menu in Google Spreadsheet, lists info about the document as "Last changed ... by anonymous", the file view in Google Drive lists the author as André H Banen.
Googling that name shows that he is or used to be somewhat of a guru within the Google Docs community. That could explain the content of the file, as it is probably random bits of example spreadsheets used in examples in some help group. What I don't get is why it shows up in my search results. Could it be that since the document is from the old Google Docs codebase it is treated differently somehow?
