• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu sang) OR (chieu sach))) OR (hieu lang)) - hanh tranh cua hang dong tinh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu sang) OR (chieu sach))) or (hieu lang)) - hanh tranh cua hang dong tinh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu sang) OR (chieu sach))) or (hieu lang)) - hanh tranh cua hang dong tinh toan ban*.
