• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc hieu) OR (hoc thieu)) manh - hanh trang va ((nhung phuong) OR (thi phuong)) dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc hieu) OR (hoc thieu)) manh - hanh trang va ((nhung phuong) or (thi phuong)) dan toan cau".
• Adding a wildcard symbol may retrieve word variants: ((toc hieu) OR (hoc thieu)) manh - hanh trang va ((nhung phuong) or (thi phuong)) dan toan cau*.
