I live in a country which uses a language I don’t speak but Google defaults to regional results in spite of my language being set to English. All other engines give me really poor results (not that Google was giving good ones, the image search has really gone to shit since they started populating it with AI stuff).
Search bangs let you search using any search engine from duckduckgo. So you can type “!g” before your search to search Google. “!w” for wikipedia, “!a” to search Amazon, etc. They have a page on duckduckgo that lets you search all the different search bangs, most every website with a search is included and has multiple search bangs that work. If you don’t remember any of the shortened commands, you can usually safely fall back on a longer one (ie if you don’t remember !a for Amazon you could do !amazon).
