An example of Tweet metadata being backfilled while generating the Search index. Accordingly, these timeline details are subject to change. Note that the underlying Search index is subject to being rebuilt. If you identify another filtering/metadata “born on date” fundamental to your use-case, please let us know. This timeline is not 100% complete or precise. The details provided here were generated using Full-Archive Search (a product of hundreds of searches). Accordingly, matching on in 2006 requires an examination of the Tweet body, rather than relying on the to: and in_reply_to_status_id: PowerTrack Operators. For example, emerged as a user convention in 2006, but did not become a first-class object or event with ‘supporting’ JSON until early 2007. In some cases Operator matching began well after a ‘communication convention’ became commonplace on Twitter. Metadata timelinesīelow is a timeline of when Full-archive search endpoint Operators begin matching. For example, if you are using Search API to access a Tweet posted in 2010 today, the user's profile description, account 'home' location, display name, and Tweet metrics for Favorites and Retweet counts will be updated to today’s values and not what they were in 2010. With Full-archive search endpoints, the querying language is made up of PowerTrack Operators, and these Operators each correspond to a Tweet JSON attribute that is indexed.Īlso, like Historical PowerTrack, there are Tweet attributes that are current to the time a query is made. It also makes use of an index to enable high-performance data retrieval. As with all databases, it supports making queries on its contents. Unlike Historical PowerTrack, whose archive is based on a set of Tweet flat-files on disk, the Full-archive Search Tweet archive is much like an on-line database. With Full-archive Search you submit a single query and receive a response in classic RESTful fashion. Full-archive Search implements (up to) 500-Tweets-per-response pagination, and supports up to a 60-requests-per-minute (rpm) rate-limit for premium, 120 rpm for enterprise. Given these details, Full-archive Search can be used to rapidly retrieve Tweets, and at large scale using concurrent requests.
These search products enable customers to immediately access any publicly available Tweet. The enterprise-tier Full-archive Search was launched in August 2015, and the premium-tier version was launched in February 2018. This article and a complementary article about Historical PowerTrack, will serve as a ‘compare and contrast’ discussion of the two Twitter historical products. That article discusses how the historical changes of the full-archive roadmap affects creating the filters needed to find your historical signal of interest.
