Hi there!
Say I have a document with the title Computer. This document contains some rems. I have tagged some of these rems with the tag 
important, while others I did not. Imagine this situation also with other rem in other documents.
Now, when I navigate to this tag (important) - because it serves me as an overview of all entries that I consider important -, how can I filter from all references this page displays only the ones concerning the document Computer?
Is there a possibility to work with search portals? Like ‘Computer’ AND ‘important’?
Still getting familiar with all the endless possibilities of RemNote 
edit: Ah, just saw this → Ability to use logical operators for searching (Queries). Yes, indeed! This is absolutely necessary… I mean, a knowledge base without a really powerful search function…? No way.
