You touched an interesting point I really haven't thought about: searching. But I think the reason I haven't thought about that is simply because on my laptop (using Linux) I can search files and documents really easily within the "Files" software and it hasn't shown any issues so far!
Sure, for this kind of stuff you must use a private repository, but there are free alternatives if you don't have or don't want to subscribe a paid plan on Github!
Bitbucket, from Atlassian, allows any free user to create private repositories and also have (recently I think) project management features (and integrates well with Trello). You could give it a try if you'd like to test this system!
Thanks for your feedback!
