I’d like to add to this request… perhaps it is more of a feature request now. I really feel like I’m hitting limits in using my notes because the search functionality is so basic. The current search is really convenient for quick use. But when I have more complex sorts of finding needs, it requires using a persistent, advanced search interface.
I know I can write queries pages but that’s not the same. I’ve made some queries for easily displaying results that I come back to over and over but it’s very inconvenient (and time-consuming) to create a query page every time I need to dome some arbitrary advanced search. With a large collection of notes (broad or deep graph) we really need a persistent advanced search pane/window.
Both Zettlr and Obsidian have different approaches to this that work very nicely. Maybe Logseq could look at those as models to inform how it might implement such functionality?
Also, I think this request corresponds somewhat with this discussion about operators.
