Does the {unique:true} option restrict the creation of new documents in the MongoDb collection?

Question

MongoDB

Hello.
If you create an index createIndex({"name":1}, {unique:true}) for the "name" field of the db.users collection, then it will not be possible to place documents with the same "name" field in it?

Answer 1

The monge documentation says that the collection will not accept the creation and modification of records if the value of the index field matches the ones already present.
