• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu tinh) OR (lieu tinh)) - ((hanh trang) or (canh tranh)) van dong cong van toan tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (lieu tinh)) - ((hanh trang) OR (canh tranh)) van dong cong van toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) OR (lieu tinh)) - ((hanh trang) or (canh tranh)) van dong cong van toan tap".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) OR (lieu tinh)) - ((hanh trang) or (canh tranh)) van dong cong van toan tap*.
