• Performing a fuzzy search may retrieve terms with similar spellings: (((("thep hanh nam dinh duc.") OR ("them thanh nam dinh duc."))) or ("thep dinh van dinh duc."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("thep hanh nam dinh duc.") OR ("them thanh nam dinh duc."))) OR ("thep dinh van dinh duc.")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"thep hanh nam dinh duc.\") OR (\"them thanh nam dinh duc.\"))) or (\"thep dinh van dinh duc.\"))".
• Removing quotes may allow a broader search: (((( thep hanh nam dinh duc. ) OR ( them thanh nam dinh duc. ))) or ( thep dinh van dinh duc. )).
• Adding a wildcard symbol may retrieve word variants: (((("thep hanh nam dinh duc.") OR ("them thanh nam dinh duc."))) or ("thep dinh van dinh duc."))*.
