search for date modified range

I have 2 databases on different computers in DTOP where I made changes to both at different dates. I want to sync them without losing those documents. They can’t be synced automatically so I am copying one and pasting it to the other computer.

Is there a way to locate recently added or modified documents? If so, I will just export those documents and add them manually to DTOP in the other computer.

Or is there a different way to do this?

Smart Group predicates such as these will narrow your review:

You might consider using DEVONthink Sync and the setting Conflicts > Duplicate Documents.
