• If you are trying to use Boolean operators, they must be ALL CAPS: thu san ((ky dang) OR (ky nang)) ha noi. hieu vu cham soc ((van nhan) OR (van phan)) viec cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu san ((ky dang) OR (ky nang)) ha noi. hieu vu cham soc ((van nhan) or (van phan)) viec cua triet".
• Adding a wildcard symbol may retrieve word variants: thu san ((ky dang) OR (ky nang)) ha noi. hieu vu cham soc ((van nhan) or (van phan)) viec cua triet*.
