DuckDuckGo (and by extension perhaps Bing, assuming identical upstream results) has some terrible results when trying to filter by all kinds of domains. There's a power tools review/news site that returns zero hits for the actual domain when searching its name (which is the same as its .com address). While for some domains even searching using the `site:` parameter will give far fewer results when paired with a query than just searching the domain name + query sans the TLD (the router firmware site openwrt.org is among such). It's a mess and reporting it hasn't any difference ime in the past 3 years. So I'd be reluctant to say irrelevant results are due to censorship unless there was more evidence.
