• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc vien) OR (hoc viet)) nganh - hanh tram van nhung cong ban ((than cao) OR (thai cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc vien) OR (hoc viet)) nganh - hanh tram van nhung cong ban ((than cao) or (thai cao))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc vien) OR (hoc viet)) nganh - hanh tram van nhung cong ban ((than cao) or (thai cao))*.
