I'm trying to use Twitter search to find all mentions of a word that DIDN'T come from a "tweet this" button. I'm trying to build a stream of all brand mentions, but I don't want to sift through all of the retweets coming from our blog, which uses Twitter's button.
As a first step, I tried looking searching for all of the tweets that came from my personal account, filtering by source:txt. It showed all of the tweets I texted in. Then source:web. It showed all of the tweets I entered on twitter.com.
But then I tried searching with source:twitterbutton. Nothing. Then source:tweetbutton. Nothing. Same with source:tweet button. I tried searching through all of Twitter's documentation on the Tweet button to see what the source: attribute is, but couldn't find anything.
When I go through my stream of tweets without filtering for the source, I see some that say via Tweet Button so I know they exist, but I can't seem to find the right source: operator to find them automatically.
FYI: I'm using the Twitter Search API Method.
Bonus points to whoever can tell me how to negate a source (return everything EXCEPT that source)
