• Performing a fuzzy search may retrieve terms with similar spellings: (("tran dan gian.") OR ((("tran dan giao.") OR ((("tranh dan giao.") OR ("tranh danh giao."))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tran dan gian.\") OR (((\"tran dan giao.\") OR (((\"tranh dan giao.\") OR (\"tranh danh giao.\"))))))".
• Removing quotes may allow a broader search: (( tran dan gian. ) OR ((( tran dan giao. ) OR ((( tranh dan giao. ) OR ( tranh danh giao. )))))).
• Adding a wildcard symbol may retrieve word variants: (("tran dan gian.") OR ((("tran dan giao.") OR ((("tranh dan giao.") OR ("tranh danh giao."))))))*.
