• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thuy anh - thanh ((tung va) OR (tuong va)) ((nhung cong) OR (dang cong)) dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thuy anh - thanh ((tung va) OR (tuong va)) ((nhung cong) or (dang cong)) dan toan cao".
• Adding a wildcard symbol may retrieve word variants: hoc thuy anh - thanh ((tung va) OR (tuong va)) ((nhung cong) or (dang cong)) dan toan cao*.
