Works best with SearchWP (but SearchWP is not necessary)

Customization

You can customize the implementation of SearchWP Live Ajax Search to a great degree, including any number of developer-defined configurations. The results are based on a template loader, allowing SearchWP Live Ajax Search to stay out of your way and letting you write the results template as you would any other WordPress theme file.

Everything is powered by adding a single HTML5 data attribute (data-swplive="true") to the input field of your search form. This happens automagically out of the box for any search forms generated from get_search_form().
