- new per-character tokenizer that is easier to read and maintain
- OR searches now supported
- grouping with ( and ) now supported
- sorting is off by default now
- searching in html is disabled for now, but may come back later
- use ? arguments instead of named arguments to ease porting to other
platforms
- field:foo is no longer wrapped in implicit wildcards
- avoid joining notes table if it not required - about 30% faster
- fixed sql injection bug in findNids()
- commands no longer have to take care of negation themselves
- commands can return nothing to immediately flag the query as invalid
The way we were handling 1 day+ learning intervals was not great - they'd show
up at the start of a new day before normal reviews, meaning the hardest cards
came first. In previous Anki versions we deliberately sorted the queue in the
opposite order to prevent that. When relearning the cards the next day, if you
failed a card and expected to see it in 10 minutes that wouldn't happen
either, as all the overdue cards took precedence.
To fix this, we put cards that are due tomorrow or later into a separate queue
(queue 3), and pull cards from that queue only after the reviews are done. In
the future it might also be nice to move overdue learning cards into that
queue automatically at the start of a session.
Using 2**32 is the technically superior solution, since it minimizes the chance of multiple notes sharing a due # (which has implicates for sibiling spacing), but the large numbers are confusing to users.
In preparation for cramming:
- add odid for storing old deck on a per-card basis
- rename edue to odue
- at the moment note.did still exists, but in the future we may ignore it and
use model.did instead
