• Performing a fuzzy search may retrieve terms with similar spellings: theo lieu tinh - ((nhanh lang) or (nhan dang)) cua cong huong tinh ((toan cau) OR (toan ban))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo lieu tinh - ((nhanh lang) OR (nhan dang)) cua cong huong tinh ((toan cau) OR (toan ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo lieu tinh - ((nhanh lang) or (nhan dang)) cua cong huong tinh ((toan cau) OR (toan ban))".
• Adding a wildcard symbol may retrieve word variants: theo lieu tinh - ((nhanh lang) or (nhan dang)) cua cong huong tinh ((toan cau) OR (toan ban))*.
