• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc hien) OR (hoc thieu)) xanh - manh ((trung va) OR (truong va)) thuong lang ban thanh chu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc hien) or (hoc thieu)) xanh - manh ((trung va) OR (truong va)) thuong lang ban thanh chu".
• Adding a wildcard symbol may retrieve word variants: ((hoc hien) or (hoc thieu)) xanh - manh ((trung va) OR (truong va)) thuong lang ban thanh chu*.
