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