Ever since going Mac in 2011, I found word-searches of either the whole system, or external (WD 'My Passport for Mac') hard drives, present a list of totally-unrelated files, despite viewing 'By Name'. The required files are often not even anywhere in the long list given, and had to be searched-for, manually, by 'Date Created'. This is a really weak feature of Macs, which they never sorted out. Don't recall the same frustration with Windows. Any ideas?
