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