• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thien) OR (hoc thieu)) tinh - hanh tang cua ((nhung tung) OR (nhung vung)) manh toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thien) or (hoc thieu)) tinh - hanh tang cua ((nhung tung) OR (nhung vung)) manh toan cau".
• Adding a wildcard symbol may retrieve word variants: ((hoc thien) or (hoc thieu)) tinh - hanh tang cua ((nhung tung) OR (nhung vung)) manh toan cau*.
