• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xay hoi. hieu ve cac du tan ((anh thai) OR (anh tai)) ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xay hoi. hieu ve cac du tan ((anh thai) or (anh tai)) ((cua tre) OR (cua triet))".
