If I wanted to build something similar to this, on a WordPress platform, where there is faceted search that loads instantly without refreshing, anyone know of any good software that does this?

 

It's using jQuery, I think its the kind of thing that would want to be bespoke to work well due to how it would interface with the DB. I've not seen anything (plugin wise) for Wordpress that does it, its not a hard thing to built in itself. How were you planning to use it? (I mean the implementation, like to search the blog?)

 

There are many Ajax Search(Site search/Google Search) already available to use in site which loads search results without reloading the page. If you want to make your own plugin then you need to make a better plugin for business/sale.
