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