• Performing a fuzzy search may retrieve terms with similar spellings: ((nuoc sach) OR (cuoc cach)) tu nang x hoi. hieu ((ve cau) or (ve cac)) truc va danh dinh cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((nuoc sach) OR (cuoc cach)) tu nang x hoi. hieu ((ve cau) OR (ve cac)) truc va danh dinh cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nuoc sach) OR (cuoc cach)) tu nang x hoi. hieu ((ve cau) or (ve cac)) truc va danh dinh cua tre".
• Adding a wildcard symbol may retrieve word variants: ((nuoc sach) OR (cuoc cach)) tu nang x hoi. hieu ((ve cau) or (ve cac)) truc va danh dinh cua tre*.
