If it is, we'll use explain to determine the index it's using. As the name implies, single field indexes are indexes on a single field. They support queries on a single field and can support sorts on a single field. We can create a single field index for a collection by using the createIndex command. We pass in the field name that we'll include in the index with the order one for ascending. Ascending indexes can be used for both ascending or descending sorts but it's important to specify the order when using compound indexes to perform sorts…
