I searched for: !expert airspeed velocity of an unladen swallow
I got an error "Sorry, a problem occurred while processing your request. Please try again later.". If I try to refresh the page it keeps failing, and every time it duplicates my query.
If I search with a new thread it does work, however if I go back to the old threat it keeps failing.
I can post the URL that is failing, if it is safe to post it with the "thread" parameter.
If assistant fails, I would expect a page refresh should fix it, or it should state that the results are cached or something, so that user tries a new thread/search.
