Find MongoDB documents by their unique _id using the ObjectId constructor without mistakes.

[00:00] Searching for a Mongo document by its ID could be a little strange at first. So let's see why. When we have a document which has a very specific ID, let's try to search for it. Now, if we provide the underscore id and we define what the id is now we get an empty result set so the thing is we need to include this object id constructor over here so this is everything going to be exactly the same though we need to remember about this ID wrapper over the object.
