I added the content in the WordPress dashboard on the WP page labeled “Front Page”. It’s content that ought to be changed now and then, so I didn’t think it belonged in the PHP template.
I would like to have text on the results page pointing out the limits of the search and how people can find products by other means. I don’t know where to add that text. It ought to be editable by a WP admin as conditions change.
Although it may be the correct place, I thought WP was infinitely configurable about what template gets used. I can’t seem to make that happen.
