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