thong cong » trong cong, thong thong, phong chong
hoc thieu » toc thieu, hoc hien

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