It's an interesting observation. We built a full text semantic search in 2011 by reverse-indexing art search results from popular search engines and it could do things like "Cezanne watercolors" at ease.

We showed it to people and we found that one could easily trick the system with things like "Worst American Art Ever". That generates results, but shows the limits of a general semantic search in a narrow context.

Happy to hear any suggestions about how to make something like this both useful and not too easy to make look really silly.
