Thanks for your notes. The search site is made entirely in React, very sophisticated with NLP and machine learning. There is no connection needed with the WP subsite Except design similarity. I don’t even need the WP search to function. WP is just like a blog wrapped around the React site. Would you need a REST API in this case? I am thinking that WP could be installed in a subdirectory of the React site, which is only a search page and a landing page.
