In the lecture Aggregation framework at video time 2:13, she use “without” word, is it right?
Is $match filter “amenities” with “Wifi” or without “Wifi”.

From my understating about this is below.

  1. It keep out other than amenities of ‘Wifi’ thru the next stage.
  2. It keep only amenities of ‘Wifi’ can past thru the next stage.
