Perhaps you should try some spelling variations:
lakes symposium » bacus symposium
das symposium » bacus symposium, texas symposium, npss symposium
acs symposium » bacus symposium, games symposium, gauss symposium
symposium sss » symposium sas
symposium ii » symposium iv, symposium i, symposium ismis

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((( ((das symposium) OR (das symposion)) ismisi ) OR ( acs symposium ii ))) OR ( lakes symposium sss )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( ((das symposium) OR (das symposion)) ismisi ) or ( acs symposium ii ))) or ( lakes symposium sss ))".
• Adding a wildcard symbol may retrieve word variants: (((( ((das symposium) OR (das symposion)) ismisi ) or ( acs symposium ii ))) or ( lakes symposium sss ))*.
