The search probably runs off a separate full-text index in their back-end (an inverted index if you will). When people post public tweets these probably get enqueued to be added to the index, so they will be included in search. They just need to delete all tweets from the index an account once it's made private. Maybe their index is append only, or it's very computationally expensive to remove old records (which is usually true for these data structures), so they've opted not to do this yet.
- lethain 18y agoThus far they don't delete tweets from the search results even after they have been deleted within twitter itself, so I suspect they are append only as you suggest.
- ja2ke 18y agoIt's frustrating that search includes deleted tweets. It's depressingly often for me that a Twitter search results page has at least one duplicate result because someone posted twice to fix a typo.
