Overlapping Tag Search for Building Your Second Brain

Currently, tags are like folders, rather than overlapping tags. The advantage of overlapping tags is that you can use them to make connections you otherwise would not have been able to see.
In remnote you could say that tag search is like this:
But for Obsidian tag search look like this:

If you want to search by the overlap between all three tags, it can’t be done within remnote.


For example, assume I am jotting down notes about the Zettelkasten method, and I want to connect the idea to a rem that has Active recall, Zettelkasten, and spaced repetition tags:
The rem that would be the connection would be:

If I want to easily find this connection using tags, I can only search by Active recall:
OR Zettelkasten:
OR spaced repetition:
For that last image, if I try to also add the active recall or Zettelkasten tags to narrow it down, it doesn’t work because Those tags are not a subset of spaced repetition.

Clearly, in all three of these examples, you can find the connection that needs to be made anyway, but when there are a lot more notes it gets much harder.

##===You can scroll down if you don’t care about the zettelkasten method==##

Now here’s the kicker: there is a reason I have not yet seen anyone using the Zettelkasten method with remote before: tags are used like folders.

Here is the Zettelkasten method:
Basically, you have input come in through content and ideas and jot them down through “fleeting notes”. When you create more detailed notes you create a reference system for those notes through tags and references like usual within remnote.

If I want to make a connection when I am generating content, it is much more difficult to do that since my brain does not think in folders. It thinks in terms of the overlap between concepts. Thus, the relations between concepts have to be done manually rather than having the help of a search function to search for the overlaps between those concepts.
