Sorry for the delay. I replied at breakfast and then had to go out for the day.
I think others have given better replies than I have, but just to observe that I find it is pretty quick to create an Agent once you are used to them, and I find them quite handy because I quite often want to search for the same thing more than once. Usually because I have forgotten what the result was. There is a shortcut to create an agent, and you can set up a text replacement, activated by a key combination like “qqfnd”, which will put in the syntax for the search criteria. You can also expand Agents by adding criteria when you need. Equally, as you add data or content, new items may be added to the search results (if they fulfil the search criteria). So they are always up to date.
