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