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