hint() does not support strings?

[nainy]

It seems like this is indeed the case, unless I'm missing something.
https://docs.mongodb.com/manual/reference/method/cursor.hint/#cursor.hint

According to mongodb documentation ^ , it is possible to pass a string (index name) to the hint() method.

Would really love this to be implemented, to be honest.

I can't reproduce this issue. Just add test case for hint in #108.
If the string is not a valid index name, it will be rejected.

The index name looks like age_1 or age_-1
Make sure you have created the index prior to the query. Otherwise it will be rejected.
