@Expression validation and case sensitivity

how many times can i use the OR operator? just once?

heres what im trying to do. how can i use more than one expression? and is this syntax below right?

@Expression(value = "userName IS WORD", errorCode = "username.has.spaces")
@NotBlank
@Length(min=3, max=20)
@Expression(value="userName NOT IN 'administrator', 'admin'," +"'support', 'help', 'helpdesk', 'customer support', 'customersupport', 'service', " errorCode = "username.taken")
private String userName;

try {
userService.registerUserIfValid(user, !result.hasErrors());  
} catch (DuplicateRegistrationException dre) {
if (dre.isUsernameTaken()) {
result.rejectValue("username", "not.unique",
new String[] { "Username" }, null);  
}
if (dre.isEmailTaken()) {
result.rejectValue("email", "not.unique");
}
}
if (result.hasErrors
