• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"international case for mechanical sciences, courses and lectures\") or (((\"international case for technical sciences, courses and lectures\") OR (\"international context for technical sciences, courses and lectures\"))))".
• Removing quotes may allow a broader search: (( international case for mechanical sciences, courses and lectures ) or ((( international case for technical sciences, courses and lectures ) OR ( international context for technical sciences, courses and lectures )))).
• Adding a wildcard symbol may retrieve word variants: (("international case for mechanical sciences, courses and lectures") or ((("international case for technical sciences, courses and lectures") OR ("international context for technical sciences, courses and lectures"))))*.
