• Performing a fuzzy search may retrieve terms with similar spellings: (("ve cach thuc dan nguoi") or ((("tu sach hoa den nguoi") OR ("tu sach ha den nguoi"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("ve cach thuc dan nguoi") OR ((("tu sach hoa den nguoi") OR ("tu sach ha den nguoi")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ve cach thuc dan nguoi\") or (((\"tu sach hoa den nguoi\") OR (\"tu sach ha den nguoi\"))))".
• Removing quotes may allow a broader search: (( ve cach thuc dan nguoi ) or ((( tu sach hoa den nguoi ) OR ( tu sach ha den nguoi )))).
