Ahh, I see that now. I just entered in 9/1/20 for the date and then got 37 main records. Then the Recipes list was fully populated. Got it now. Just wasn't intuitive in how it was supposed to be used. Put taco in search term, and just the taco recipes are listed in the dropdown.
I'm still not sure what that gains you as there are no actual recipes there, just the names of the recipes. As long as it is doing what you want, I guess that's all that matters.
