Hi Mirco,
Thank you for reaching out to us. Regretfully there is no option display the search query using dynamic content however you can achieve the same result by adding the following code in your functions.php file:
// Shortcode to display search query
function display_search_query() {
return get_search_query();
}
add_shortcode('search_query', 'display_search_query');
This will register a shortcode [search_query]
you can use this shortcode in your search result layout to get the search query for example, you can use it like this:
Search results for [search_query]
Please note that the code provided above serves as a guide only and is to help you in getting started so implementing it and maintaining the code will be out of our support scope and for further maintenance for new possible versions of the theme that may cause the customization to break, you will need to hire a developer.
Hope this helps!
