• Performing a fuzzy search may retrieve terms with similar spellings: cao cho manh - hanh ((((trinh cua) OR (trinh luan))) or (trinh luat)) thong cong dan toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: cao cho manh - hanh ((((trinh cua) OR (trinh luan))) OR (trinh luat)) thong cong dan toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cao cho manh - hanh ((((trinh cua) OR (trinh luan))) or (trinh luat)) thong cong dan toan ban".
• Adding a wildcard symbol may retrieve word variants: cao cho manh - hanh ((((trinh cua) OR (trinh luan))) or (trinh luat)) thong cong dan toan ban*.
