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