You don't need the Free form expression for this.
Instead of providing a single expression in that search, click on the
magnifying glass and open Advanced search.
On 'Find items which match' select 'any of the following conditions'
Click Add conditions as many times as you need, and fill the boxes.
That way you can have a condition of Sender contains Marjorie and a
second condition of Sender contains Trello.


As for your problem with the Free form expression, they use a prefix
notation, not infix. You would need
   or:(f:trello f:marjorie)
