How to use Google Books API to search inside a specific book for specific keyword?

Question

I would like to search inside a specific book for a specific keyword. Is this possible with the Google Books API? I've read the documentation and cannot find an endpoint that will allow me to do this, nor any mention of this functionality. I know that the Google Books website allows users to manually "search inside" a book, but does anyone know if it's possible to do via the Google Books API?
