• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((tranh hang) OR (tran hoang)) va ((nhung cong) OR (thong cong)) dan phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((tranh hang) OR (tran hoang)) va ((nhung cong) or (thong cong)) dan phan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((tranh hang) OR (tran hoang)) va ((nhung cong) or (thong cong)) dan phan cau*.
