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