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