Google introduces better related terms and longer snippets
Longer snippets are something I've wanted for a long time. I hate it when I get really close to finding the entirety of the information I need without actually having to click through to a result, but the snippet comes up one word short. That frustration should be greatly decreased with longer snippets that attempt to show more of your search terms together. This new feature kicks in when your search contains 4 or more words.
The improvements to related terms mean that Google can now more accurately suggest other searches that relate to your search terms. The example they give is searching for principles of physics, which now suggests searches for things like quantum mechanics, special relativity and the big bang. This should make narrowing down your results and finding what you want on Google even easier.
