• Performing a fuzzy search may retrieve terms with similar spellings: o chau tinh - ((((hanh trang) OR (minh trang))) or (thanh trung)) va nhung cong dan toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: o chau tinh - ((((hanh trang) OR (minh trang))) OR (thanh trung)) va nhung cong dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "o chau tinh - ((((hanh trang) OR (minh trang))) or (thanh trung)) va nhung cong dan toan cao".
• Adding a wildcard symbol may retrieve word variants: o chau tinh - ((((hanh trang) OR (minh trang))) or (thanh trung)) va nhung cong dan toan cao*.
