• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced in oto-rhino-laryngology\") or (((\"advanced in oto-rhino-otolaryngology\") OR (\"advanced in otto-rhino-ottolaryngology\"))))".
• Removing quotes may allow a broader search: (( advanced in oto-rhino-laryngology ) or ((( advanced in oto-rhino-otolaryngology ) OR ( advanced in otto-rhino-ottolaryngology )))).
