Is there any way to search the messages for a specific date?
Yes.
Click on the filter icon (funnel shape) to the right of the search button. Then click the Any Time button and select Custom Range...
Dang. I see the bugs are back.
If in your Account Preferences you've selected a Date Display other than MM/DD/YYYY then the entry of a custom date range will be ... finicky. I haven't exactly worked out what the deal is, whether it matters if you edit the text or use the calendar drop-down, for example, but I often as not get no results when I have my preferred Date Display of YYYY-MM-DD.
I reported this to support
once
long ago, and I thought it got fixed. Maybe I didn't test well enough, or maybe it has reverted.
