They certainly don’t seem to me to be working! Searching for neurotrauma gives the expected results, but searching for @Neurotrauma delivers zero results - specifically, this:
{

"search_metadata": {
"completed_in": 0.004,

}
}
You said “When you search for a mention like “@Neurotrauma,” your results will consist of recent Tweets that mention @Neurotrauma” - well, I’m afraid that’s not correct, there are no results. But if I try a different account name it works fine, e.g searching for mentions of @BBC gives plenty of results.
There’s not been a lot of activity recently on the @Neurotrauma account, and the most recent post is only just inside the usual 7 day cutoff for API searches. I’ve seen suggestions that accounts that don’t do much get squeezed out of the results list, but when you’re searching for a specific account that seems to be an odd thing to do.
