• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky dang xay hoi. hieu ((ve cam) OR (va cam)) xuc ban anh ((hai cau) or (hai chau)) tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky dang xay hoi. hieu ((ve cam) OR (va cam)) xuc ban anh ((hai cau) OR (hai chau)) tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky dang xay hoi. hieu ((ve cam) OR (va cam)) xuc ban anh ((hai cau) or (hai chau)) tren*".
