• If you are trying to use Boolean operators, they must be ALL CAPS: (("acs symposium ies") OR ((("das symposion sas") OR ((("bacus symposium semi") OR ("bacus symposium sagt")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"acs symposium ies\") or (((\"das symposion sas\") or (((\"bacus symposium semi\") OR (\"bacus symposium sagt\"))))))".
• Removing quotes may allow a broader search: (( acs symposium ies ) or ((( das symposion sas ) or ((( bacus symposium semi ) OR ( bacus symposium sagt )))))).
• Adding a wildcard symbol may retrieve word variants: (("acs symposium ies") or ((("das symposion sas") or ((("bacus symposium semi") OR ("bacus symposium sagt"))))))*.
