On the Search page, one of the options is “Since Yesterday” (other pages seem to have other choices) When is this? If you query the Search at 10:05 PM Wednesday and say Since Yesterday, does it go back 24 hours - to 10:05 PM Tuesday, or, does it get everything from Tuesday (yesterday)?

It means the last 24 hours. I did a quick test. I searched for the word “post” in MPSIMS “since yesteday” and ended up with 81 threads. The time frame was from 2-27-01 10:26 PM till 2-28-01 10:15 PM.
And I did check with the same search for the “past 5 days” and there were plenty of other threads within a few minutes of the cut-off.

Thanks, **JimB** , there’s nothing like actual research, especially if someone else does it.
