Thank you for your kind words!
Google autocomplete unfortunately only gives generic results back, based on the words typed in. It has no connection with your site, it just basically a keyword information sent to google, and it sends back other possibilities.
You can however change the autocomplete source to your post titles, which might be what you are looking for. On the Autocomplete & Suggestions -> Autocomplete panel, try selecting the “Post Titles” option instead of “Google Keywords”: https://i.imgur.com/XwOanwe.png
That way if the search phrase matches the beginning of any post title, it should display the full title as the suggestions. Please note that this may cause a bit of performance drop. In that case, you can optimize the performance by this guideline from the documentation.Best,
