The default search operation is the AND boolean operation:
tag:#tag1 AND tag:#tag2
I see all notes that have both tag1 and tag2. (Intersection)
I’d like to be able to also do the OR operation.
tag:#tag1 OR tag:#tag2
This would show all notes that have either tag1 or tag2. (Reunion)
There could also be an AND+OR operation that does both.
tag:#tag1 AND+OR tag:#tag2
This would show both their intersection and reunion.
- The notes that have both tags in common are displayed normally.
- The rest are displayed faded out.
Using colors, it would be nice to be able to see the selected tags as a kind of Venn Diagram – overlapping tags grouped in the middle, and non-overlapping tags grouped to the sides.
tag1 (tag1 AND tag 2) tag 2
