Today, 2023-04-01, I searched using Google via these search terms:
site:geekhack.org "fav mouse"
And it returned a search result as I expected it to:
I tried that using DuckDuckGo search but got this:
Is my syntax incorrect? How can I ensure that DuckDuckGo produces same or similar results as Google?
I speculate that Google has "scraped" that website but DuckDuckGo has not. So if that is the case, then the subquestion is: What syntax do I use to tell DuckDuckGo to start "scraping" that website so that at some point in the future it will return the results?
