How "Date Opened is Today" tracks documents (solved)

My mistake: I have quite a few documents opened but haven’t sorted the results by using the “Opened” column. The question is solved

I have multiple main windows opened for the same database. I enter the following search string in the search field of one main window. But it seems the results only show the opened documents (opened and closed, or stay opened) in the same think window but not the opened documents in other think windows of the same database even after I reset the search by deleting the string and reenter it again. Is there a time lag for updating the results?


The search string: kind:any openingDate:Today scope: the database name
