• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sai) OR (su dai)) ky ((tang xa) OR (trang xa)) hoi. hieu ve cam duc van anh tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sai) OR (su dai)) ky ((tang xa) or (trang xa)) hoi. hieu ve cam duc van anh tai cua tre".
• Adding a wildcard symbol may retrieve word variants: ((su sai) OR (su dai)) ky ((tang xa) or (trang xa)) hoi. hieu ve cam duc van anh tai cua tre*.
