BBM - I have a little on that, but not much.
I think in the following one they are talking about the woods, or brush area surrounding the HOG. (Sorry the link doesn't work anymore).

Sweep Woods For Woman After Scent Picked Up
UPDATED: January 30, 2006
Police officers in Orlando, Fla., continued a search of a heavily wooded area Monday near the location where 24-year-old Jennifer Kesse's abandoned car was discovered last week after a scent was picked up in the area, according to a Local 6 News report.
Kesse, who works for Westgate Resorts in the Orlando suburb of Ocoee, Fla., is considered a missing and endangered adult after she mysteriously vanished last week.
"One of the two strongest clues that the Orlando Police Department is sharing with the media is the scent that was picked up in the woods," Local 6 News reporter Samantha Knapp said.
Sunday, officers on horseback methodically went through the brush near a condominium complex in southwest Orlando where Kesse's 2004 Chevrolet Malibu was located. ...

But then, in 2009 (at least I think they are talking about 2009), notice the different area given but dogs hit there, too.
Rough transcript from portion of video:
“Wesh 2 reporter live now where this new search is happening. It’s near the intersection of OBT (Orange Blossom Trail) and Oakridge. So, David, tell me what lead police search teams to that area?” “Well, they are really only saying that they have had a tip that takes them to this area. Now, they point out that they have had a thousand leads since her disappearance, but, obviously, this is a tip that they believe is very credible. We want to zoom in—we want to show you the area that is central to the search. We can tell you after talking more extensively with police and actually talking with Jennifer’s father that cadaver dogs came in here. Dogs with a good track record and they have hit on this area. And that is exactly why the search has intensified.”

So, I don't know; but I think you make a good point on this. How many old cases do we see where they came so close to finding the victim in an early search, but somehow just missed.
Even the Elizabeth Smart case comes to mind--they were searching so close, she could hear them calling her.
Also, there was one more search noted as a field but it is the site of a huge Walmart today. If you haven't listened to the podcast link before, it explains about it and most of the searches. You might find it interesting.
