• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sai) OR (vu hai)) ky hoang van hoe. hieu ve cham xuc van hanh ve ((cua tre) OR (cau tren))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sai) OR (vu hai)) ky hoang van hoe. hieu ve cham xuc van hanh ve ((cua tre) or (cau tren))~".
• Adding a wildcard symbol may retrieve word variants: ((vu sai) OR (vu hai)) ky hoang van hoe. hieu ve cham xuc van hanh ve ((cua tre) or (cau tren))*.
