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