This seems like a weird glitch - am I doing something wrong? When I do this saved find:
. . . I get 105 donors. When I look up the same criteria a different way I get 108 donors. The second way is step by step: find for MailingList=Yes, then find for GiftDate>1/13/2015 and constrain set, then find for GiftDate<1/13/2016 and constrain set again. For some reason when I do the finds this second way and sort on last name, I get 108 donors, including 3 donors who didn't give in the range at all:
Shouldn't both of those ways to find that date range achieve the same results?
