• Performing a fuzzy search may retrieve terms with similar spellings: vu sac ky nang xa hoi. hieu ly nam thuoc vat hanh vi ((cua te) or (((cua tuc) OR (cua thuoc))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky nang xa hoi. hieu ly nam thuoc vat hanh vi ((cua te) OR (((cua tuc) OR (cua thuoc)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky nang xa hoi. hieu ly nam thuoc vat hanh vi ((cua te) or (((cua tuc) OR (cua thuoc))))".
• Adding a wildcard symbol may retrieve word variants: vu sac ky nang xa hoi. hieu ly nam thuoc vat hanh vi ((cua te) or (((cua tuc) OR (cua thuoc))))*.
