I'd be curious to know where the Walmart is and what searches you tried.
Jan. 15th I was curious if the walmart was going to be a supercenter so I searched, "fallston md walmart," & "will fallston md walmart be a supercenter." As you can see either result does not show the most relevant and recent info about my query, rather it's littered by prominent job sites. Though on a search for "will fallston md walmart be a supercenter," i see the six result to be http://www.belairnewsandviews.com…
I'm just now testing this query, but when I did [fallston md walmart], there is a really comprehensive article at http://www.exploreharford.com/news/3074/work-start-fallston-... that shows up at #5. That article mentions that "The new road will lead into a 147,465-square-foot Walmart, which has been planned with a possible 57,628-square-foot expansion" Then I did the search [walmart supercenter size square feet]. The #1 and #2 results are both pretty good, e.g. the page at http://walmartstores.com/aboutus/7606.aspx says that an average store is 108K square feet, and supercenters average 185K square feet.
As a human, I can deduce that 147K square feet (with 57K square feet of potential expansion) implies that it will probably be a supercenter, but it's practically impossible for a search engine to figure out this sort of multi-step computation right now. My guess is that in a couple months when the store opens up, this information will be more findable on the web--for example, somewhere on Walmart's web site. But for now, this is a really hard search because there's just not much info on the web.
I appreciate you sharing this search. I think it's a pretty fair illustration of how peoples' expectations of Google have grown exponentially over the years. :)
