FindOneOptions

The most documents the server may examine for the request, counting every document it reads, not only the ones it returns. An index lowers the number. A positive integer.

The most milliseconds the server may spend on the request. The server looks at the clock while it examines documents, so a limit can be passed by a little before the request stops, and a long sort or group is not interrupted once its documents are read. A positive integer.

This is separate from the client's requestTimeoutMS, which gives up waiting for the answer. Keep requestTimeoutMS larger than maxTimeMS, or the client may stop waiting first.

The fields to return. See Projection. The result type follows the projection when it is written inline.
