Only two houses for sale in South Bay?

After searching the MLS this morning, I found two houses for sale in the South San Mateo, Redwood City area. The criterias used for searching were: built after 1980, detached or duet housing. The results that came back are two houses built in 2001, and their prices are listed as $580,000 (3 bed, 2 bath) and $768,000 (4 bed, 2 bath). This can't be right.
