• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chu xanh) or (chuc nang)) - hanh tang van ((nhung cong) OR (thong cong)) dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu xanh) OR (chuc nang)) - hanh tang van ((nhung cong) OR (thong cong)) dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chuc nang)) - hanh tang van ((nhung cong) OR (thong cong)) dan toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chuc nang)) - hanh tang van ((nhung cong) OR (thong cong)) dan toan cau*.
