Site search documentation

The site search documentation and imagery seems to be based on an old version of the dashboard and refers to sections that have been renamed / moved.

Also I had to delve into the code of the datocms-search library to work out how to set the environment for the API call!

But loving site search it’s so useful for a site like mine where the pages are made up of so many different nested components!

thank you for the feedback! We’ll review it as soon as possible!
