I'm using "ytsearchdate10:termA termB termC" in a script run every 48 hours via cron to download certain videos that are uploaded to Youtube on a daily/weekly basis.

From what I can tell --match-title works as logical "or", meaning that "--match-title term1|term2" will match a video with either term1 or term2 in the title. Is there a way to make --match-title function as logical "and"? So that a video would only download if term1 and term2 were both in the title?

Thank you for your help!

--match-title accepts arbitrary regular expression, e.g. term1.*term2.

@dstftw is right, but term1.*term2 requires term1 to come before term2. To match both ignoring order use positive lookaheads:
