If you're building a site with advanced registration and want to allow frontend search of registered users, I’d recommend checking out the Member Directory module we recently released.
It’s designed exactly for this type of use case:
Real-time search with multiple filter options
Fully customizable fields pulled from the Joomla User Profile plugin
Responsive layout, ready for multilingual use (12 languages including RTL)
Secure input validation and caching for performance
It works well alongside your RSForm Pro setup if you're using it just for registration, but it can also integrate directly with standard Joomla user profiles – so no need for complex coding or custom components.
