Chapter 2: MongoDB Indexes / Understanding Explain

Hello everybody,

Minute 05:03 in the video :

Kirby explain that we don’t have any indexes to support our sorting that’s why we made an in memory sort. SORT_KEY_GENERATOR

I think the opposite, we have already created indexes to support our sorting, that’s why we checked only 7 and returned 7 docs. ExplainStats output shows that.

Can anyone clarify to me please, or it’s just an error from video translator ?

Thanks !
