We may not respond to all requests for support when the issue in question (in your case, indexing) was already solved by another staff member before we saw your ticket. I'm sure you can understand, when we have to address hundreds of tickets a day, lower priority issues may not immediately get a response as we only have so many man-hours in the day.
I would also like to not encourage opening a thread for people to air out their grievances with our support email, as we've already highlighted several ways in which we are working on it. Having additional voices complain about the same problem that we are working to address does not encourage or engender additional man hours and staff for the problem, it just amplifies community complaints that we are already hard at work trying to address, and these kinds of threads are ultimately not productive to the improvement of our services; they only add additional stress on our staff that is already stretched pretty thin. Thanks for understanding.
