Google gets longer snippets, semantic related search terms

Google announced yesterday that it has made two changes to its search result pages. First up are longer snippets when you enter a search query with more than three words, this improvement aims to help you to pick the website that offers the most relevant information.

The second improvement is a bit more complicated, Google has deployed a new semantic technology which reportedly offers better understanding of associations and concepts related to your search. Currently, it's used to provide more useful related searches:

Starting today, we're deploying a new technology that can better understand associations and concepts related to your search, and one of its first applications lets us offer you even more useful related searches (the terms found at the bottom, and sometimes at the top, of the search results page).

For example, if you search for [principles of physics], our algorithms understand that "angular momentum," "special relativity," "big bang" and "quantum mechanic" are related terms that could help you find what you need.
