When I type in multiple search terms in the search box I expect to see results each of which contains all of those words and to see the words highlighted in the search results. This is the standard Google has set and pretty much all search engines that I can think of work this way, but apparently not the SO search engine. This makes it very difficult to avoid asking duplicate questions, as the search results are largely irrelevant unless you search for a single specific word.
Case in point, this very question has probably been asked but when I search for the string "search all words", whether with or without quotes, I don't see any relevant results. I get results containing the word "search" and a few of them even contain the word "words", but I can't see any that contains "search" and "all" and "words".
So how do I find relevant results when searching for multiple terms?
Edit: I appreciate people pointing out my mistake about how the Google search works (you learn something new every day!), but the question wasn't actually about the Google search - it was about the Stack Overflow search. The point is that I expect to see results relevant to all the terms I entered, not just some of them, and I don't see those on Stack Overflow. Is it possible to force it to match all the terms?
