$match homework - getting a wrong number

I’m getting 24 documents rather than 23. I manually checked all 24 and looks like the criteria match. I’m guessing if an extra document has been added recently. Not sure how I can check my query…

There are a couple of threads related to this “24” conundrum. Suggest you search and go through them, and if you’re still uncertain, post back.

Edit: Here’s one such thread, there are a few more too.

Thank you. It’s been resolved.
