Isn't that more a question of adding to the mix frequent scraping of

- a few thousand news-sites (like nyt.com, bbc.co.uk),

- a few thousand very popular blogs (based on what influencers people search for),

- a handful of social media sites (e.g. Twitter),

- a few hundred databases in areas like weather, airlines, sports (like ATP for people who look for Wimbledon results today)?
