• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky sang) OR (ky nang)) ma hoi. hieu he nam thu dia danh ((sai cua) OR (hai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky sang) OR (ky nang)) ma hoi. hieu he nam thu dia danh ((sai cua) or (hai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((ky sang) OR (ky nang)) ma hoi. hieu he nam thu dia danh ((sai cua) or (hai cua)) tre*.
