Wording of Questions

Please avoid wording ambiguous questions like this:

“We must explicitly remove _id in a projection.”

The real answer is either yes or no depending on the context. No you do not have to remove _id explicitly if you want to keep it. If you want to remove it, then yes you must do it explicitly.



I fell for this too. The context is needed to warrant the ‘must’ attribute.

Hi @robkat,

Point taken. We will make it more clear.

Thanks for the feedback.
