Relevanssi doesn’t by default index the headings in Visual Composer. The vcex_heading shortcode Visual Composer for the headings stores the heading text inside a shortcode attribute. By default, Relevanssi does not index shortcode attributes.
In this case, indexing the shortcode attribute is necessary. Fortunately, it’s easy to fix with a simple function added to your site:
add_filter( 'relevanssi_pre_excerpt_content', 'rlv_shortcode_attribute', 8 );
add_filter( 'relevanssi_post_content', 'rlv_shortcode_attribute', 8 );
function rlv_shortcode_attribute( $content ) {
return preg_replace( '/\[vcex_heading.*?text="(.*?)".*?\]/im', '\1 ', $content );
}After you add this function, rebuild the index. Now the headings are included in the index. This function is added to two hooks: relevanssi_pre_excerpt_content handles the excerpts and relevanssi_post_content the indexing.
