I have created more than 40 tags in 3 main topics : authors, topics and shape (video, article, citation, etc.). Now I want to find a note by filtring with tags but I can only filter by one, I don't understand. I've seen a YouTuber who could search first with one tag (all the results appear) and then he could click again on tags to add a second tag in order to have a more precise search. In my mobile phone and in the web application I can't do that, so I need your help guys. (Sorry if my english is not good, I'm french).
