• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu tinh - anh hung va thong cong tan ((((tranh chap) OR (tranh cua))) OR (trinh chat))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - anh hung va thong cong tan ((((tranh chap) OR (tranh cua))) or (trinh chat))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu tinh - anh hung va thong cong tan ((((tranh chap) OR (tranh cua))) or (trinh chat))*.
