• Performing a fuzzy search may retrieve terms with similar spellings: (("thang tien cong may") or ((("thang tien luong my") OR ("thanh vien luong my"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("thang tien cong may") OR ((("thang tien luong my") OR ("thanh vien luong my")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"thang tien cong may\") or (((\"thang tien luong my\") OR (\"thanh vien luong my\"))))".
• Removing quotes may allow a broader search: (( thang tien cong may ) or ((( thang tien luong my ) OR ( thanh vien luong my )))).
• Adding a wildcard symbol may retrieve word variants: (("thang tien cong may") or ((("thang tien luong my") OR ("thanh vien luong my"))))*.
