How about distance between words. (Smith married to Ellen - search for those words close to each other )
How about sounds similar. Like burger.
What about saving complicated searches.
On the other hand, back in the 90s it was a practical necessity to use extended search syntax with services like AltaVista to find anything because search engines were basically terrible. Google on the other hand has and continues to expend considerable effort to ensure such syntax is unnecessary 99.9%+ of the time.
Consequently very few people know it any more. Combine this with the fact that in order to use the extended search syntax effectively you often need at least some understanding of what you're searching for (e.g., at least the ability to discern bad vs. good information), and you can quickly see why the average Joe is going to end up seeing and quite possibly believing the false information.
(I, for example, not being any kind of foodie, only know that it takes much longer than 10 minutes to caramelise onions specifically because I saw a friend who is a foodie do it a few years ago. He specifically made the point that it takes ages, otherwise you lose the sweet flavour. If that hadn't happened I'd believe it takes 10 minutes because Google said so.)
The minus operator either no longer works at all, or it just penalizes results without eliminating them.
For Google it's a minus sign. (sometimes it's the word NOT)
E.g. "onions -news" (without the quotes) will search for the word onion and not return any sites that have the word news in them. This can have false positives so youd need to play around with the words.
False positives because non news sites may have the word news and news sites might not have that word.
