• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc thieu) or (thi chieu)) xanh - ((hanh trang) OR (hanh trinh)) cua khong cong dan toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (thi chieu)) xanh - ((hanh trang) OR (hanh trinh)) cua khong cong dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (thi chieu)) xanh - ((hanh trang) OR (hanh trinh)) cua khong cong dan toan cao".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (thi chieu)) xanh - ((hanh trang) OR (hanh trinh)) cua khong cong dan toan cao*.
