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