Filtered deck with just added cards today

I would like to have a filtered deck with only cards added today for initial studying. This works fine the first time I use the deck, but if I add more cards and rebuild the filtered deck then the previously added cards are also included. I.e. what’s the trick for a filtered deck to only include new cards with added:1, if no longer new – after studying and new cards are added? I suspect another query entry has to be added.

Finally had time to read the section on search keywords: Anki Manual
added:1 -rated:1

I.e. this filtered deck is use to practice new cards added today but after they are trained, they should go back to their individual decks for future day studying.
