• Performing a fuzzy search may retrieve terms with similar spellings: (((("lang tho tinh.") OR ("dang thuy tinh."))) OR ("hoang thuy tinh."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"lang tho tinh.\") OR (\"dang thuy tinh.\"))) OR (\"hoang thuy tinh.\"))".
• Removing quotes may allow a broader search: (((( lang tho tinh. ) OR ( dang thuy tinh. ))) OR ( hoang thuy tinh. )).
• Adding a wildcard symbol may retrieve word variants: (((("lang tho tinh.") OR ("dang thuy tinh."))) OR ("hoang thuy tinh."))*.
