Thank you for the log-in details, I have checked the search configurations.
I see you have searches enabled to return posts and pages as results. However there are no posts, and only a very few pages there on the site, which are not categorized by location in any ways.
Is there any specific custom post type you want to search instead? I'm guessing real estates, but I can't see any custom post type on the back-end, or anything real estate related at the moment. I'm guessing the solution would be to have a custom post type that stores the real estate information, and having a custom taxonomy that categorizes it by countries. Then on the search back-end, you can actually configure the plugin to exclude or include results from specific categories only.Best,
