As of some recent update on the ps4, at least since january, I am unable to enter any text on duckduckgo's search bar in the built in browser. The keyboard pops up briefly then vanishes. It likely works with an external keyboard, but the onscreen one refuses to appear. Google's search bar work's fine, the PlayStation's built in search works fine(but uses google), in site search engines powered by google work fine. But I have been unable to use duckduckgo on the ps4 since at least then.

I was capable of doing this before and regularly did. But, from what i've been able to tell, my web searches must all go through google now, either through the built in search feature or the browser.
