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