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