When I first built this macro, I left off the date range options because I didn't know how best to add them. Keyboard Maestro doesn't have a date-picker input option, and I thought it would be too onerous to manually type in the date range on every search.
Both of those things are still true, but I found what I consider a reasonable middle-ground (and a few minutes of free time to actually add it to the macro). It now pre-populates with a date range of the last 30 days, and the date range option toggled off.
Easy enough to adjust if you need it. Out of your way if you don't.
