Automatically filter the_excerpt() to use SearchWP Term Highlight to find a proper global excerpt
function searchwp_term_highlight_auto_excerpt( $excerpt ) {
global $post;
if ( ! is_search() ) {
return $excerpt;
// prevent recursion
remove_filter( 'get_the_excerpt', 'searchwp_term_highlight_auto_excerpt' );
$global_excerpt = searchwp_term_highlight_get_the_excerpt_global( $post->ID, null, get_search_query() );
add_filter( 'get_the_excerpt', 'searchwp_term_highlight_auto_excerpt' );
return wp_kses_post( $global_excerpt );
add_filter( 'get_the_excerpt', 'searchwp_term_highlight_auto_excerpt' );
