One option would be to just block https pages (or vice-versa), you can do that by adding the string "https://" to the path matches to ignore option in the website import (it's under 'More Options').

Of course you'd need to reimport.
Another option (that doesn't require you to reimport the source) is to filter out https results

I'll also record a feature request to optionally treat https and http URLs as the same.
