I tried to replicate an exact issue I had last week, but I can't which is interesting. I knew I had read a doc days earlier. I could not find it by partial title matches, content searches, nothing. I had to search email for "so and so shared a doc" to get back to the document. Of course, now I can find it the expected way. I routinely need to search things that are buried in docs, like our intern program. This was another one where I couldn't quite remember the title of the doc nor who wrote it. I searched and searched variations of things containing "intern" and even though I had been in the document within the last couple of weeks, I just plum couldn't find it. I had to go back to a calendar invite to find the doc. Part of the problem could be that sometimes people write things different. I might look for "precap," a part of a doc title I'd expect for interviews, but someone else stored it as "interview pre-read" and so I can't find it. That's why I like document hierarchies / trees for finding things. I can go HR -> interviewing -> $something_more_if_needed and browse a couple of files and find what I want. Labels are cool for when something fits into multiple locations in the tree.
