• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((thieu sang) OR (hieu lang))) OR (chieu sang)) - anh tang cua han tong van quan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((thieu sang) OR (hieu lang))) or (chieu sang)) - anh tang cua han tong van quan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((((thieu sang) OR (hieu lang))) or (chieu sang)) - anh tang cua han tong van quan ban*.
