We welcome edits that make the post easier to understand and more valuable for readers. Because community members review edits, please try to make the post substantially better than how you found it, for example, by fixing grammar or adding additional resources and hyperlinks.

I think you gave the best answer. I was going to jump in but; you created a lot of value here. Good answer.

Thank you, an alternative to .find() is .findOne() - .find() returns and array, while .findOne() returns the first record it finds(object), ignoring the rest. This is good in cases where you are looking up documents with a unique field - like by email, or ID.

@darshanan do you mean how do you search through values in nested keys on a document? If so it's db.collections.find({"keyOne.keyTwo":"search"})
