The sort direction is not important, and MongoDB can traverse the index in any direction.In conclusion, composite indexes are very efficient in point queries, which directly locate the age, do not need to sort the results, and return the results.
Multi-valued query (Multi-value-query)
Db.users.find ({' age ': {"$gte": +, "$lte": 30}})
Finds documents that match multiple values. Multi-valued queries can also be understood as multiple point queries.A

The sort direction is not important, and MongoDB can traverse the index in any direction.On the other hand, compound index is very efficient in point query, it is not necessary to sort the result and return the result.
