I started looking around to find techniques for efficient searching Google Drive. Here is what I found.
I wanted to find all the docs that Doug owned. I typed this into the search bar: owner:dbarton
I know there was a doc created after a certain date. I used this to search: after:2015-01-03
About a year ago I created a document that talked about the Promethean software. I'm not sure what the document was called but I'm pretty sure I mentioned the word Promethean somewhere. All I did to find what I was looking for was to put quotes around the word Promethean.
