• Performing a fuzzy search may retrieve terms with similar spellings: theo chu sach - hanh ((mang cua) or (manh cua)) dang cong ((dan toan) OR (manh toan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu sach - hanh ((mang cua) OR (manh cua)) dang cong ((dan toan) OR (manh toan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu sach - hanh ((mang cua) or (manh cua)) dang cong ((dan toan) OR (manh toan)) cau*".
