Despite having a Twitter Developer Account, I still can not seem to get Twarc to retrieve tweets older than thirty days, and I'm wondering what I'm doing incorrectly. I created and was granted by Twitter a developer account called nfc4ds. The account has a number of subscriptions, and one of them is called "Search Tweets: Full Archive / Sandbox". I then dutifully created a twitter application complete with an API key and secret. I then authorized Twarc (a Python tool/library) to use the application. I then used Twarc to search Twitter with this query: from:ericleasemorgan The result was a set of a few tweets. I then used the following query, but the results were empty: (from:ericleasemorgan) until:2019-12-31 since:2019-01-01 What am I doing wrong? Is Twarc unable to query things from the past? Does my subscription not really include the full archive? -- Eric Morgan University of Notre Dame
