It’s not a big deal… for now, because most of the time when I limit DDG results I ask for 1 year back (for solutions that are sort of recent but not ancient).
I would never limit results to just the last week, and typically posts that are that fresh won’t have enough accumulated knowledge so even if they pop up on the results they’re not really useful.
Again, that’s just my experience. I’m curious if others have similar ones.
