How to Find a Book by Subject

Backstory:

After reading Is it known how the first viruses formed?, I was immediately struck by the idea that it would make a great book. Either in science-fiction ala Michael Crichton, or as popular science ala Stephen Pinker, Michio Kaku, etc. I'm now really looking forward to reading many future hypothetical novels on this subject, which unfortunately, I have no idea how to find.

Now, I'm not wanting a list of recommendations or "best-of", just a a representative sampling from the various people that frequent the site. Unfortunately per Are all list questions off-topic?, that would clearly be off-topic. Then I read Q&A is Hard, Let’s Go Shopping! and decided it would be better if I knew how to find the books I wanted, period. So question:

Question:

How can I reliably match a query comprised of an extremely specific topic and perhaps a few representative keywords, against a comprehensive list of books.

Example:

• Subject: virus origin, evolution


• Keywords: LUCA, RNA


• Genre: Fiction | Popular Science


• Sort: rating

Would also be nice if you could demonstrate using that particular example :)
