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

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