I first reported the problem of tweets missing from search results in 2019, three years ago.
There was a problem back then that resulted in my account being suspended. I supplied what @TwitterSupport wanted and my account was unsuspended. A few months after my account was unsuspended, I noticed my tweets prior to these events were no longer visible in search. I think they should have been, both from a moral or ethical point of view, and I suspect normal procedure in that situation includes restoration of all old tweets to visibility in search, but they were not reindexed due to an error, an oversight.
