That middle thread was started by you. The other 2 threads were started 2 months before yours. So, essentially what you're saying is you need to learn how to use the search.
Anyway, most people don't even know how to use the search. Back in August when the tech gremlins did the update, they somehow messed up the search. For 5 years, I used quote marks in my searches, but after the update, the quote marks wouldn't work. Any search that included quote marks would return zero results. Now, they work, but only on short terms and only in about 5% of my searches.
