Thanks, @mwra ! I actually tried that as well, but so far it’s not producing query results.
To back up and give some context, I’m using this as a way to query prototype-applied notes without links that have been generated in a file that I’ve been working on in the Basic set up questions for Map project post. I’ve created a folder titled “Agents - Timeline” that contains query agents for each prototype.
But want to also create an agent that contains three sets of prototype-applied notes (which is the basis of my post query), which I’m then hoping to organize with TimelineBands and timeline preferences. So, I thought the using & $Prototype would be better than | $Prototype for these purposes.
