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