Alter search bar to crawl content and pick up headers as well as products
I've recently finished developing my site, a resource for student revision and work, but being content-heavy and few products I wanted the search tool to be able to crawl through my websites page content [most importantly the headings e.g. <h2>, <h3> and <h4>] as well as the relevant products?
Is there any way of altering the default search tool? Or does anyone know any good extensions which would perform this?
