• Performing a fuzzy search may retrieve terms with similar spellings: ((ho chieu) OR (hoc thieu)) sach - hanh ((truong cao) or (trung tuan)) dong duong va phan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) sach - hanh ((truong cao) OR (trung tuan)) dong duong va phan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) sach - hanh ((truong cao) or (trung tuan)) dong duong va phan cau*".
