Writing a fail2ban multiline regex

I’m not sure if this the correct regex, but i’m trying to add multiple lines at the ignoreregex

Here are the config lines in my ddos.conf:

[Definition]
failregex = ^<HOST> -.*"(GET|POST).*
ignoreregex =.*(robots.txt|favicon.ico|jpg|png)
             ^<HOST> -.*"(GET|POST).*(Googlebot|bingbot)

Is the code is correct what should i add to multiply lines
