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

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 ((((("acs symposium ii") OR ("gauss symposium ii"))) OR ("lakes symposium ismis"))))) OR ("das symposium sieds")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"bacus symposium isvc\") or (((((\"acs symposium ii\") OR (\"gauss symposium ii\"))) or (\"lakes symposium ismis\"))))) or (\"das symposium sieds\"))".
• Removing quotes may allow a broader search: (((( bacus symposium isvc ) or ((((( acs symposium ii ) OR ( gauss symposium ii ))) or ( lakes symposium ismis ))))) or ( das symposium sieds )).
• Adding a wildcard symbol may retrieve word variants: (((("bacus symposium isvc") or ((((("acs symposium ii") OR ("gauss symposium ii"))) or ("lakes symposium ismis"))))) or ("das symposium sieds"))*.
