• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sach) OR (((chieu sang) OR (hieu lang)))) - manh trung can song song van tan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sach) or (((chieu sang) OR (hieu lang)))) - manh trung can song song van tan ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sach) or (((chieu sang) OR (hieu lang)))) - manh trung can song song van tan ban*.
