Back when I subscribed to O'Reilly I had a bookmark set up to search there with Packt excluded. Otherwise no matter what I searched for the results were clogged up with Packt-slop.

I think this is precisely the Packt strategy though - to always overwhelm the search results, whether its O'reilly, Amazon, etc. They do this by their sheer volume of low quality titles. Everything about that company and their content is complete shit.
