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