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