The first query[1] should match messages containing both "Saúde" and "Geap" (sans the double quotes) in the subject, but does not. 1: 'subject:("Saúde" "Geap") OR subject:xplitz' Also note that the fourth query[2] should have AND as the implicit boolean operator, because 'subject:' is not a boolean prefix. You explained in the other thread the implicit OR operator only applies for search terms with the same /boolean/ prefix. 2: 'subject:"Saúde" subject:"Geap"' Regards -- - I am Brazilian.
