I'm not quite sure what it was, it was maybe 3-4 weeks ago. I think part of the problem is that different searches return different results: "2x4 birch plywood" returns the correct results in the first two slots - 2'x4' birch plywood in 1/2" and 3/4". "2'x4' birch plywood" returns those two correct results above in the 3rd/4th positions as you noted. As a customer, this is a signal that I need to be real good at searching on HD's website and start thinking up clever permutations for my searches. Also, IIRC, at the time it also returned 2"x4" lumber either at or near the top of the results. Well, if I put "plywood" in the search string, I expect plywood, not results for every length of 2"x4" lumber that HD carries. I was pretty irritated at the time and I'm actually surprised that "2x4 birch plywood" even appears in the top row of the results.
