Perhaps you should try some spelling variations:
"das symposium ismis" » "das symposium isaac", "texas symposium ismis", "lakes symposium ismis", "npss symposium ismis"
"games symposium ii" » "lakes symposium ii", "gauss symposium ii", "cities symposium ii", "games symposium iv", "games symposium i", "games symposium ieee"
"das symposion sieds" » "das symposion des", "das symposion wien"
"das symposium sieds" » "das symposium series", "das symposium sas", "das symposium sss", "texas symposium sieds", "lakes symposium sieds", "npss symposium sieds"
"bacus symposium isvc" » "bacus symposium isaac", "abacus symposium isvc", "backs symposium isvc", "baus symposium isvc"

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: (((("bacus symposium isvc") OR ((("games symposium ii") OR ("das symposium ismis"))))) OR ((("das symposion sieds") OR ("das symposium sieds"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"bacus symposium isvc\") or (((\"games symposium ii\") or (\"das symposium ismis\"))))) or (((\"das symposion sieds\") OR (\"das symposium sieds\"))))*".
• Removing quotes may allow a broader search: (((( bacus symposium isvc ) or ((( games symposium ii ) or ( das symposium ismis ))))) or ((( das symposion sieds ) OR ( das symposium sieds ))))*.
