What triggers the error message "The pattern that you entered appears to be too general - can you make it more specific for this technology?"? I tried to add a technology for the use of rel="nofollow", using an XPath expression //a/@rel[contains(., "nofollow")] , and got that error message. What do I need to do to make it more specific?

Good question, I think rel=nofollow must match too many websites. I'll look into it.
