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