How to use Google Drive advanced search to find files that are not shared?

Question

I'm trying to find files in Google Drive that are:

1. Owned by me
2. Located in "My Files" (not shared folders or Team Drives)
3. Not shared with anyone

The advanced search dropdown has options for 1 and 2, but I can't figure out the "Not shared with anyone" piece.

The Google Drive advanced search documentation has options like to: to find files that are shared with specific people, e.g. to: notme@example.com. But, I need the opposite of this, something like -(is:shared).

As an experiment, I tried to search files that are "owned by me" and "not shared with a specific person" by using the - and to: options:

owner:me -to:notme@example.com

This simply returned the message "None of your files or folders matched this search", which makes me think you can't use - and to: together.

Manual workaround

My current workaround is to use owner:me and search in "My Files" and manually scan the files that do not have the "shared" icon to the right of the filename, but I would love to find a way to filter all these files using advanced search.

Answer 1

I think I figured it out, put the email addy in parenthesis: owner:me -to:(xxx@gmail.com) This works too: ((owner:me) AND (-to:(xxx@gmail.com))

However, it did NOT work when I tried to add the "parent:" variable to search in a specific folder, in only worked in My Drive no matter where in the string that variable was, or if I used the AND configuration.
