Hi!
The live results page loader is only an experimental feature, it highly depends on the theme and site structure, please note that.
To make it work, you need the same exact search instance on the results page. You can either use it as a widget, or place it somewhere as a shortcode in the sidebar, whichever you prefer.
Then, in your case, you need to enter this to the live results loader selector section:
[code].traveltour-content-area[/code]
This will select this area for replacement for the search results.
