• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) ty hang ca hoi. hieu ((ve cam) OR (ve cac)) tuc va hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ty hang ca hoi. hieu ((ve cam) OR (ve cac)) tuc va hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ty hang ca hoi. hieu ((ve cam) OR (ve cac)) tuc va hanh vi cua te*".
