• Performing a fuzzy search may retrieve terms with similar spellings: so ((sanh v) OR (sanh va)) nang co hoi. lieu va pham duc van hanh lam ((chau triet) or (cau trieu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sanh v) OR (sanh va)) nang co hoi. lieu va pham duc van hanh lam ((chau triet) OR (cau trieu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sanh v) OR (sanh va)) nang co hoi. lieu va pham duc van hanh lam ((chau triet) or (cau trieu))".
• Adding a wildcard symbol may retrieve word variants: so ((sanh v) OR (sanh va)) nang co hoi. lieu va pham duc van hanh lam ((chau triet) or (cau trieu))*.
