I would like to use a filtered deck to study all different subjects I have in Anki at once, using other decks to mainly control review/new cards flow of a particular topic (via deck options).
My problem is that search is:due only finds cards that are to be reviewed today (as opposed to learnt) and is:new matches all unseen cards.
So, what search term would return all cards that are scheduled for today, including review and new ones?
Studying default deck proved unsatisfactory as the order of cards was predictable, very much so in AnkiDroid.
