What do you mean Google “changes the search terms”? I tried “blacks killing cops” in Google, DuckDuckGo, Bing, Yahoo, DuckDuckGo, and Yippy and didn’t see any of them changing search terms. (I DID see “cops killing blacks” one time in the Google search bar, but I think I mistyped it myself. I repeated it several times and it does not change the search phrase.)
I’ve never seen any search engine change the actual search words or phrase.
What is telling is the searches in the six search engines. All of them returned many of the same articles and videos, but the results in all do seem to somewhat tilted toward the reverse, “cops killing blacks.” Because this is so uniform, it appears to me that the people producing “cops killing blacks” material are doing a better job of Search Engine Optimization rather than the search engines being biased. I wouldn’t expect the search algorithms at six separate search engines to all be biased in the same direction — UNLESS they are all using some common search engine under the hood.
There’s also a difference in the number of hits (shown in millions below):
Google 1.85
Yahoo 14.3
Bing 14.3
DP no number
DDG no number
Yippy 14.3
IXQuick no number
IXQuick is the former name for StartPage.com.
No number result really pleases me.
I am very happy with it.
