I hope you are well today and thank you for your question.
The search results page is displayed by the search.php file of the hello-elementor theme that you are using on your site so the plugin doesn’t control how the search results page structure and its text will be displayed on the search results page but your site hello-elementor theme controls it.
You can change this developing custom code in the search.php file of your child theme by contacting the theme author or consider hiring a developer to develop it for you. You can hire a developer from any freelance site or WordPress agency.
You can also consider hiring us to develop it for you using the form https://ivorysearch.com/custom-work/
