searx and searxng are not search engines, and searx is more private (searxng collects info from users, which searx never wanted to). AFAIK duckduckgo is neither a search engine on its own, it uses blink…
To tell the truth, only yacy and sightnet have own index(database).
Others are meta-search engines. They work like proxy. It’s called meta search. (https://en.wikipedia.org/wiki/Metasearch_engine)

iirc Mojeek also has it’s own database
Mojeek has it’s own index. DuckDuckGo, Qwant and Brave have a partial index mixed with meta search results.
