Is _id index used for the update rather than the find, i.e. this call searches for the document twice?

This call doesn't search for documents twice! My understanding is that find just creates a View on the collection, and then the update command performs the search (with the specified index) and the update.

In this case I am confused: how would the _id index be used with a query on name?

I'll think of a clearer example.
| - The session to use for this operation. | ||
| * - ``upsert`` | ||
| - Whether to upsert if the document doesn't exist. Cannot be used on | ||
| ``find_one_and_delete`` operation. |

What about the :return_document that was in the example previously, does it still work?

Yup! Thanks for pointing that out.
