In searches on google.com and duckduckgo.com, you can add a clause “site:some-domain” to your search.
For example, a duckduckgo search “site:wikipedia.org end-of-life” will offer many articles that the native Wikipedia search can’t find. Some of those titles include Product lifecycle and End of Life Vehicles Directive
I wanted to be a clever and ask the search engines to look at itself to give me an answer. I quickly discovered that asking Google “site:google.com” is incredibly useful.
Most of the results come from feedproxy.google.com. In other words, this style of query searches Google’s vast collection of blogs and news feeds.
It’s an awesome tool!!! It narrows my searches in a very useful manner.
And I’ve only scratched the surface. For example, in an advanced search query “Last update” does what it should. Google will find blog posts from the past year, month, week or 24 hours.
