• Performing a fuzzy search may retrieve terms with similar spellings: toc ((hieu manh) or (dieu hanh)) - hanh trung cua duong hoang ((van toan) OR (van tan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((hieu manh) OR (dieu hanh)) - hanh trung cua duong hoang ((van toan) OR (van tan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((hieu manh) or (dieu hanh)) - hanh trung cua duong hoang ((van toan) OR (van tan)) cau*".
