I created a smart group containing all documents modifier within the last quarter. I was expecting to see a book in that list which I had added some annotations to (highlighting text). Does this count as modifying the document? I would have thought so, but I don’t see that document in the list.
Yes, that’s a modification. Maybe your annotations are a little bit older or the book is not in the search scope of the smart group?
In the info pane the book says modified 06/01/22. Could that be the problem? I just added a bit of highlight to test, and it updated the date modified to today - so that works. Not sure what the problem was. Maybe my previously highlights were entered longer ago.
That’s one possibility. Other ones are that the modification date was changed e.g. via the Info > Generic inspector or by a smart rule or a script.
