Posting only when keywords mentioned?

Hi there, I haven’t found a way but perhaps it’s changed a bit since I last used it. I disabled it last time because it simply posts too often to my pages when I really only want certain topics of articles pushed to my social networks.

I run a tech support company which duplicates a few feeds from TNW and potentially others when needed. Is there a way to have it only publish articles where “Apple”, “Microsoft”, “Facebook”, and “Google” are in the post titles, for example?
