Google is a name that most of the people might be knowing and its the most used search engine in the world. This search engine is the best as anything and you need to know can be found on google. There is a very popular catch phrase that if you want to know anything "JUST GOOGLE IT" this shows that information about anything and everything can be found on google. There is also a very nice thing about google search engine that you only type the first word of your search and google will show the related and possible thing you need and its pretty much accurate.
I don’t think so that there is any worst aspect of the search engine because it gives you result of what you are searching for so if you search bad things you get bad things and if you search good things you get good things.
I have always used google search engine if I need any information needed as it loads fast and displays the results quickly as compared to other search engines. Its results are also accurate comparatively.
