Google is really a powerful search engine!

I’ve been using Google search engine for a few years, cause I can’t always found what I want by Yahoo search engine. Google search is a really powerful search engine that I can search what I want in a specific language, period, web site, file type, region etc. When having a good skill or familiar with the search engine, I can gather information easily and faster than to find books in a library. Josephine also introduced a branch search engine of Google, Google Scholar, to us. In my opinion, it doesn’t help me as much as the Google search. It’s still a beta version and hope it would improve well in the future.
