• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty nang cai hoa. thien van cau phuc ((va thanh) or (van hanh)) ((tai cuu) OR (tai buu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang cai hoa. thien van cau phuc ((va thanh) OR (van hanh)) ((tai cuu) OR (tai buu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang cai hoa. thien van cau phuc ((va thanh) or (van hanh)) ((tai cuu) OR (tai buu)) tre".
• Adding a wildcard symbol may retrieve word variants: su sach ty nang cai hoa. thien van cau phuc ((va thanh) or (van hanh)) ((tai cuu) OR (tai buu)) tre*.
