• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu sang) OR (thu sang)) - hanh manh cua thong cong san ((toan tap) OR (thanh cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu sang) OR (thu sang)) - hanh manh cua thong cong san ((toan tap) or (thanh cac))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu sang) OR (thu sang)) - hanh manh cua thong cong san ((toan tap) or (thanh cac))*.
