• Performing a fuzzy search may retrieve terms with similar spellings: doc hieu manh - hanh trung cua ((tong cong) OR (cong cong)) dung ((hanh ca) or (hanh cat))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu manh - hanh trung cua ((tong cong) OR (cong cong)) dung ((hanh ca) OR (hanh cat))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu manh - hanh trung cua ((tong cong) OR (cong cong)) dung ((hanh ca) or (hanh cat))*".
