Comparison of the old and new Twitter search results
Aside from doing it on its main timeline, Twitter is updating what results you see when you search for something on its service. Instead of going with reverse chronological order, Twitter is basing it off relevance to the user. According to Twitter’s early trials, this approach results in users engaging more with the service. In a blog post, Lisa Huang, senior software engineer for search quality, says the change was made because “the most recent results may not be what the searchers are looking for.” You might get a better grasp of a certain topic from popular tweets or other more relevant tweets than the most recent ones.
Twitter relies on its algorithm and your user behavior to collect this information. It seems to be using roughly the same programming it uses for your main timeline but perhaps with some adjustments since it has to pull information from the social network’s entire database. Now, when you pull up a search on Twitter the different categories (most popular ones, the latest, by people, photos, videos, etc.) will now be algorithmically controlled.
