Hi!
It looks like those listings are actually posts, which is good. However it doesn’t look like the listings site is part of the network installation, that must be the problem. On the listings ajax search amin page I cannot see any of the multisite instances. It appears to me as the listings site is a fully separate WordPress installation, that would explain why the search can’t find the database entries. The ftp also confirms my theory, as there are wordpress files under the public_html/listings directory, and that directory shouldn’t even exist on a multisite install.
Unfortunately it is not possible to cross-search one WordPress instance from another, the sites must be connected with a multisite installation – this is the reason why you can’t see results from the listings site on your main site.
Best,Ernest Marcinko
