Description
Could you provide a further explanation on the following texts in Documentation? Thanks!
"There are some situations where the prefix indexes may offer better query performance: for example if z is a large array.
The
{ x: 1, y: 1, z: 1 }index can also support many of the same queries as the following index:
{ x: 1, z: 1 }"
