Extra content in movies collection?

MongoDB University M121: The MongoDB Aggregation Framework
#1

I’ve written a filter against the movies for the chapter one match lab, and get 24 results instead of 23. A manual inspection of each document returned shows that each documents meets all criteria. I did this exercise last week with no problem, but I needed to write it again because the next lab “inherits” from it. The automated test does not pass.

I’m out of ideas, and I’m wondering if maybe the actual content of the database has changed such that the test is no longer valid.

What do?

My apologies. Nevermind. When manually inspecting the output, I missed a spot. No further help is needed.

Thank you very much, I got it.

In this case, we can use $nin instead.
