As you can see from the mode line, you can type C-h m for help. It says you can use regular expression to match the buffer name, so this pattern might work for you:

^.*.txt\|.*.log

or more accurately

^.*\.\(txt\|log\)

    It's very long expression. It's very difficult for me to remeber it. It's will be good if expression is more simple. Something like this: .log|.txt

    @Alex you can ask the maintainer of helm for help by filing an issue on github github.com/emacs-helm/helm
