From getting started to mastering v4.0 in Google search (1)

■ 1. Preface
I learned about Google in the first half of 2000. Before that, I used AltaVista to search for English information, while Sina was often used to search for Chinese information. But since Google was used, it became my Favorite Search engine. I would also like to thank Cao Xi, a netizen, for recognizing Google because of his strong promotion.
I remember that in the summer of 1996, when I first came into contact with the Internet, I was conquered by the magic. That kind of feeling is really amazing. After experiencing the crazy WWW surfing and crazy BBS addiction, I realized that the Internet has a profound impact on me, but it is still because of the changes in learning methods.
How can we describe this change? In the past, you usually need to store enough knowledge in your stomach. If necessary, you need to extract the required information from the massive amount of information. This kind of learning method has created many talented people to learn more than five cars. However, in the new era where the information field is much larger than the "Four Books and Five Classics", it is out of date to learn how to swallow massive amounts of information in advance. For example, when we arrive at a large book city, we often feel overwhelmed. The old learning methods need to be changed to adapt to the age of information explosion. It seems more efficient to learn with a clear purpose, that is, to know what to learn and to search for answers with a specific purpose. I may call this a learning style. The old ones are called pre-learning ".
However, there is a premise for the implementation of "learning. First, the learners are required to have an all-encompassing information library for extracting information of various purposes at any time. Second, a powerful information retrieval tool is required to extract information from the database efficiently. Obviously, the Internet can act as the massive information library, and the search engine is an excellent tool to find the fire of light.
"To do good deeds, you must first sharpen your tools ". There is only one Internet, and more than N search engines. Some search experts say that the so-called search is "using the correct tools and methods to find the right content in the right place ". However, for ordinary people, it is unlikely to master many search engines. It is even more urgent to use one or two relatively powerful representative tools to achieve the vast majority of search targets. Different strong emerged in different periods. For now, we are very lucky to have:

It is best to have some basic foundation of Boolean algebra, such as "and", "or", and "non. However, even if you do not have this knowledge, you do not have to worry about it. If you practice those instances, your doubts will be solved. For those who are new to online search, you may want to read this article from start to end. But for those who have a certain search base, you only need to jump to find the information you need. In addition, you can also refer to the Chinese Google Book: Baidu.
