• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu can) OR (thu canh)) ky dang xay hoi. hieu qua ca xuc van ((hanh di) OR (hang di)) ca viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu can) OR (thu canh)) ky dang xay hoi. hieu qua ca xuc van ((hanh di) or (hang di)) ca viet*".
