In the viewer search window enter a search term, anything, "land" is a good choice. That will bring up all results. Along the top of the results you will be able to filter by land sales. Once in the land sales results you will be able to filter the results further. It will then be immediately obvious that the filter options are not very helpful to find $/sqm prices. Also, you must search for land using a search term, like "land". It's not possible to browse land sales like in the old 1.23 search. If the old 1.23 search is still available (I've not used 1.23 for a while) I would recommend using that for searching for land for sale.
