Twitter creates new search system, users can search old tweets

All of your old tweets are searchable on Twitter.

The company presented a new system that allowed users to look for older public tweets on Tuesday, according to Twitter’s company blog. They previously had a “real-time index” that saved tweets for one week, but their entire index was so much larger and continued to grow greatly.

Tech Times reported that people could search for old tweets by different means, such as a program from Apple called Topsy, but they weren’t as easy to use. Reportedly, the new search system wasn’t brand new, but an update on the Advanced Search on Twitter where users could search tweets based on criteria like keywords and senders, among other options.

Technologically, Twitter’s blog explained in detail about the four major parts of the new system. Those parts included “a batched data aggregation and preprocess pipeline; an inverted index builder; Earlybird shards; and Earlybird roots.”

Such uses for the search engine and old tweets were explained by Tech Times, including investigators using someone’s old tweets for evidence or establishing motive for a suspect or journalists looking for people to report on.
