With the end of the school semester looming, I missed putting a post out about this update. Early in December, Google made searching Google Drive simpler. If you've ever lost a file and couldn't remember where you saved it, this is a lifesaver!
Now users can click in the "Search Drive" box and instantly click an icon to search for PDFs, Docs, Sheets, Slides, Drawings, etc.... You can also click More Search Tools to refine your search to include Date Modified, Keywords, Owners, Shared With and Location.
This release is already available to Gmail users. GAFE Users on Scheduled Release will see this update in January. If you don't see it, check with your Google Apps Admin to verify release time.
