• Performing a fuzzy search may retrieve terms with similar spellings: (((("nuoc sach hoc may nguoi") OR ("nuoc sach hoi may nguoi"))) or ("so cap thu giap nguoi"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("nuoc sach hoc may nguoi") OR ("nuoc sach hoi may nguoi"))) OR ("so cap thu giap nguoi")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"nuoc sach hoc may nguoi\") OR (\"nuoc sach hoi may nguoi\"))) or (\"so cap thu giap nguoi\"))".
• Removing quotes may allow a broader search: (((( nuoc sach hoc may nguoi ) OR ( nuoc sach hoi may nguoi ))) or ( so cap thu giap nguoi )).
