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