Thanks for the feedback as I find it really interesting on how others structure tags as I am going through a setup of Evernote Business for my business and struggling with appropriate level of detail on tags and also how to keep my arms around it so random and meaningless or duplicate tags don't appear.
Really though, I have no issue with my technique being brittle (at least when used by me as an individual, it would be more problematic in a team environment). I don't create notes 10, 5 or even 3 at a time. I create notes one at a time and I have to title all of them individually anyways, so it is easy to keep a "table of projects" list open in the background, copy and paste the title of the project in the title of the new note. For example: YYYY/MM/DD - Note Description - Project Title. The system works very well for me and hence I'm not really asking for advice on the use of tags to change it, I'm just looking for a feature from Evernote (which not being a professional programmer may or may not be feasible) in which you can embed a search query as a hyperlink in a note. This would be useful even for folks that organize there projects with tags. I could then save a hyperlink on my Note that has all my projects listed out and have a link in the table that performs the search query to show all the relevant notes. For now I just use saved searches and it works fine. When I am done with the project I can delete the saved search, but at the same time if I ever wanted to go back and review the project for something I can still recreate the search.
Also, there is a problem with organizing tags in a tree with Evernote Business, it appears they don't allow you to tree them in Business version (if they do I haven't figured out how yet). Also the iOS versions don't let you view your tags by tree, only alphabetically which is another request I put in somewhere else. I tend to have a higherarchy of tags by category. I.e. - people (list of relevant people), Status (draft, final, rev 1 ,rev 2), Urgency (I try to use the Eisenhower Matrix so four tags: Urgent, Important, Not Important, Not Urgent) and Type (Letter, E-mail, Contract, Phone Call, Meeting Notes, Agenda etc). because of this organization system I wish you could see the trees in iOS but you cant.
I do try to keep all my tags very high level and not get specific with dates.
