Perhaps you should try some spelling variations:
"bacus symposium series" » "bacus symposium semi", "bacus symposium sas", "bacus symposium sss"
"acs symposium sieds" » "acs symposium sas", "acs symposium sss", "acs symposium semi", "lakes symposium sieds", "games symposium sieds", "gauss symposium sieds"
"das symposium ismis" » "das symposium isaac", "das symposium isvc", "das symposion ismis", "texas symposium ismis", "lakes symposium ismis"
"acs symposium irs" » "lakes symposium irs", "games symposium irs", "gauss symposium irs", "acs symposium iv", "acs symposium i", "acs symposium iii"
"das symposium ii" » "das symposion ii", "texas symposium ii", "lakes symposium ii", "das symposium iv", "das symposium i", "das 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: (((("acs symposium irs") OR ((("das symposium ii") OR ("das symposium ismis"))))) OR ((("acs symposium sieds") OR ("bacus symposium series"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"acs symposium irs\") or (((\"das symposium ii\") OR (\"das symposium ismis\"))))) or (((\"acs symposium sieds\") or (\"bacus symposium series\"))))*".
• Removing quotes may allow a broader search: (((( acs symposium irs ) or ((( das symposium ii ) OR ( das symposium ismis ))))) or ((( acs symposium sieds ) or ( bacus symposium series ))))*.
