• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - anh quang ((tuan nhung) OR (thuat nhung)) ((cong dang) OR (cong dong)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - anh quang ((tuan nhung) OR (thuat nhung)) ((cong dang) or (cong dong)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - anh quang ((tuan nhung) OR (thuat nhung)) ((cong dang) or (cong dong)) toan cau*.
