• Performing a fuzzy search may retrieve terms with similar spellings: (("tu sach hoc dau nguoi") or ((("tu manh duoc le nguoi") OR ("tu doanh duoc le nguoi"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("tu sach hoc dau nguoi") OR ((("tu manh duoc le nguoi") OR ("tu doanh duoc le nguoi")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tu sach hoc dau nguoi\") or (((\"tu manh duoc le nguoi\") OR (\"tu doanh duoc le nguoi\"))))".
• Removing quotes may allow a broader search: (( tu sach hoc dau nguoi ) or ((( tu manh duoc le nguoi ) OR ( tu doanh duoc le nguoi )))).
• Adding a wildcard symbol may retrieve word variants: (("tu sach hoc dau nguoi") or ((("tu manh duoc le nguoi") OR ("tu doanh duoc le nguoi"))))*.
