Hi @naviji, I had a look at your GSoC contributions to Joplin, thank you very much for your hard work. I was brought here by a comment on this thread as I’m really interested in the tag-based search functionality described there.
I believe I’m right in thinking your search engine will allow searching for tag intersections using something like tag:"first tag" AND tag:"second tag". Would it be within the scope of your project to code in the ctrl-click tag searching that I and at least a few others would so love to see become a part of Joplin?
