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