I strongly recommend everyone read Luhmann's original paper [1] on Zettelkasten.
What I got from it is that, the process is less about storing/retrieving information, but more about building a system that can surprise you - the way ideas emerge when you brainstorm with others. These others being people with the same level of knowledge as you - so, not the kind of information flow that happens between an expert and a beginner, but between peers who have access to the same kind of information, but simply look at things differently.
For some reason, every Zettelkasten system out there focuses on the mechanics, and in my opinion, not enabling the original intent of the approach. Not that I have a solution to the problem.
