is there any way to help it evolve?

Cough up a heap of money for machine learning research and datacenter infrastructure.

They are using the Bing api if I recall correctly, which should give better results than unrelated porn images for whatever you were searching for, though. As a developer I would recommend you to give them specific feedback when you encounter these situations, so they know about it and have a chance to fix the underlying issue.

Personally, I'm also using Startpage, which is decent most of the time, altough for some queries the results seem weirdly nerfed.
