You have a good point that I will keep in mind.
This is what it looks like (just starting, not complete and not in the right order, and hotkey triggers for each menu item).
A Keyboard Maestro generated menu based search triggered from anywhere inside and out of DevonThink (if out of DevonThink, will activate DevonThink first). Extremely fast. IMO faster than typing in the search pane with the manual in front of me, or navigating through filters. Obviously not all options are there , but the end result will cover 90% of my searches.
