Is it possible to use the plugin in a non-post template? Please check the link I provided. I want to use the search function as if you are searching for a product. But in my case, it’s a regular content, not a post.
Do you mean like searching the contents of the page as if it was separated into multiple results?
I’m afraid that is not possible – each page/post or post type is considered as single entity in wordpress and is stored as a single row in the database. Therefore searching any contents on a single page will always return that single page as the result.
