Ability to search for Twitter audiences discussing a topic based on the number of followers they have - ideal for identifying gen pop conversations VS influencers. For example, if we wanted to search for people interested in eating healthy food:
("healthy eating" OR "weight watchers) AND (twitter_followers:<3,000) - would provide what can be considered a gen pop sample of people on Twitter with less than 3K followers discussing health food.
("healthy eating" OR "weight watchers) AND (twitter_followers:>10,000) - would provide what can be considered an influencer sample of people on Twitter with more than 10K followers discussing healthy food.
