Querying a non-existing field, returns all documents, instead of returning nothing

Describe the bug
Querying a non-existing field, returns all documents, instead of returning nothing.

To Reproduce
Steps to reproduce the behavior:
Say we have a users collection like this:

users { name: String }

Notice that users document only has a name property and not an email property, Now if I try:

db.users.find({ email: 'something'})

It will return an empty array as a result, but If I give the same query to the paginate function, it will return all documents in the Users Collection. Looks like it's throwing out non-existing properties and the query will become {} so it returns all documents.

Expected behavior
Behave like default Mongoose or MongoDB behavior and return nothing, or do not empty out the query?

UPDATE: I tested MongoDB's default behavior, not mongooses, sorry for the wrong opening of the issue, read this: #185 (comment)

Looks like the problem is mongoose's strictQuery setting being true by default since v6.0.10

Its default will be back to false from mongoose 7, until then, mongoose.set('strictQuery', false) is the solution
