I have to say that the UI confused me for a moment. The fact that what I searched didn't stay in the search box, and instead it replaced it with a new suggested search term was confusing.
Sorry you found this confusing. We show suggestions in greyed out text to encourage new searches for new things you can learn about.
The goal of this search engine is to let users both explore and search for what they need, not just search like what you can do with conventional search engines.
I think it's just a matter of the dominant elements on the page. The thing you searched is in small text beneath the very large search bar so it takes a moment to figure out what is going on. Otherwise very cool, good work!
