DataviewJS Snippet Showcase

I know a teeny tiny bit of dvjs. I have a use case for it that is probably very easy. I’d like to count the number of times a set of words or phrases show up in my “wellness” field. I want to map how many times I’ve done certain things – or logged them at any rate.

field example:
in my daily notes, in my “Bujo” folder, each day has this kind of information.
Wellness: drank water, painkillers, music.

what I’d like is to count how many times I’ve used “water,” “painkillers,” “music” etc.
my daily note title template is 2022-07-06 – Wednesday for example.

Can this be done easily? If so, how?

Thank you.
