• Performing a fuzzy search may retrieve terms with similar spellings: (("thep mang lam tinh duc.") or ((("tao bang nam trinh doc.") OR ("tao bang nam trinh co."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("thep mang lam tinh duc.") OR ((("tao bang nam trinh doc.") OR ("tao bang nam trinh co.")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"thep mang lam tinh duc.\") or (((\"tao bang nam trinh doc.\") OR (\"tao bang nam trinh co.\"))))".
• Removing quotes may allow a broader search: (( thep mang lam tinh duc. ) or ((( tao bang nam trinh doc. ) OR ( tao bang nam trinh co. )))).
