Currency of saved searches
I guess I'm being a bit lazy because I could wait and inspect, but perhaps this is of modest usefulness for reference:
When I click-launch a saved search, does it compute the search keywords (and results) afresh or does it load the search content as it was at the time it was saved, without incorporating new results?
I've never cared enough to notice, but am digging into some details.
