You can use the find

str = "Hello, World"
if string.find(str, ",") then
  print ("Encontrou virgula.")
else
  print ("Não encontrou virgula.")
end

If the search pattern is found the function returns the position (start and end) within the string where it was found.

> = string.find("Hello Lua user", "Lua")
7       9
> = string.find("Hello Lua user", "banana")
nil
