More correct terminology, that may help understanding, would be to refer to the "S" inventory on the flights as Revenue Booking Code (RBC) inventory, which, as noted above, is only part of what's needed.

Many of us here prefer ITA Matrix, which has far more fine-grained controls and provides a lot of detailed information. Others prefer Google Flights for the speed and simplicity.
