Ask HN: Harbor Freight Spam

At least once or twice a day now, I receive spam emails with a subject line like "SurveyRegistrationConfirmation" from "Harbor Freight", "Kohls", etc.

Lots of complaints here: https://www.reddit.com/r/GMail/comments/148mjhm/harbor_freight_spam/

Google filters can't capture these because the "subject" filter can't do a partial word match for "survey", for instance.

And of course the from email and name always changes, and Google filters can't do a partial match on "harbor" or "kohl" in the from field.

Any ideas how to kill this email spam? Why is gMail powerless to capture these patterns?
