1 Introduction
I know Google in the first half of 2000. Prior to this, I search for English usually use Altavista, and searching Chinese information often uses Sina. But after using Google, it became my Favorite Search Engine. This is also grateful to Sina netizen Cao Shui, because it is because of his great promotion, it makes me know Google.
I remember in the summer of 1996, when I first contacted the Internet, the magic of the flutter was conquered. The feeling of the end of the sky is really unlikely. After experiencing crazy WWW surfing and fascinated BBS fatigue, I realized that the Internet had an influence to me or lied to the change of learning.
How to describe this change? Previous learning, generally need to store enough knowledge in the belly, if necessary, extract the required parts from massive information. This kind of learning method has created a lot of talents who "talented high, learning rich five cars". However, in the new period of the information field, it is too much to swallow a lot of information in advance. For example, we have come to a large book city, often there is a feeling of doing it. The old learning methods need to be changed to accommodate this information explosion. The purpose is clear to learn, that is, first know what to learn, then have the purpose of finding answers, this way looks more efficient. I may wish to call this as "learning", according to the old, the old "pre-school". However, the implementation of "learning" is premised. First, the learner is required to have a Bangongxian information library to draw a variety of purposes, followed, is a strong information retrieval tool to extract information from the information library. Obviously, the Internet can act as the massive information base, and the search engine is looking for a great tool for light fire.
"Experience in a good thing, must first make a tool." Internet only one, and the search engine has multiple. Searching masters say, so-called search is "in the right place to use the correct tool and the right way to find the right content". However, for ordinary people, master the possibility of many search engines seems not large. With one or two relatively strong representative tools reach most search purposes more urgently. Different times have emerged in different periods. For now, we are very lucky:

■ 4, Google Introduction
Google (www.google.com) is a search engine that is found in September 1998 by two Stanford University, in September 1998, Google Inc. founded in 1999. In July 2000, Google replaced INKTOMI became the search engine of Yahoo, in September of the same year, Google became the search engine of China Netease. Since 1998, Google has already received more than 30 industry awards. To Google's News Center (http://www.google.com/press/index.html), you can find history and news information about Google. Google's success has benefited from its powerful features and unique features:

Google has a unique picture search function; Google has a strong newsgroup search function; Google has binary file search function (PDF, DOC, SWF, etc.); Google also has a lot of surprising ideas and features that are still in development. and many more
■ 5, search entry
To make a search with Google, of course, you must first go to Google website - www.google.com; however, 163.com and Yahoo.com are actually Google search engine (for all reasons, Netease and Yahoo China are now Use Baidu Engine - this site note), just arrange the search results, and you cannot provide some feature functions, such as image search, etc. Therefore, if you want to search for a web page, use Google.com.
For the first time I entered Google, it determines the language interface according to your operating system. What needs to be reminded is that Google is stored by cookie, so if your system disables cookie, you cannot set up your Google interface.
Google's homepage is very refreshing, LOGO, the four functional modules are arranged: websites, images, newsgroups, and directory services. By default is the website search. Now in the first search practice, assume that you are a newcomer, you want to find out the search engine's whalery and search skills. Enter a keyword "Search Engine" in the search box, select the Search Chinese (Simplified) page "option, then click the" Google Search "button below (or go directly), the result is coming out.
Search: "Search Engine" Result: Searched Chinese (Simplified) webpage for search engines. There are about 707,000 query results, which is 1-10 items. Search for 0.08 seconds.
Take a closer look at the top ten of the search results, you will find that most of the link is the search engine itself, not an introduction to search engines or search skills.
Note: The quotation marks outside the search syntax in the article only enters the reference role and cannot be brought into the search bar.
■ 6, grade search
The above example is the most basic search, that is, the query contains information about a single keyword. However, you can find that in the upper example, a single keyword "Search Engine", the search information is like smoke, and most of them do not meet their requirements, what should I do? We need to further narrow the search scope and results. 6.1, search results require two and more than two keywords
The general search engine needs to be added between multiple keywords "", and Google does not need to use the plaintext "" to represent the logic "and" operation, as long as the space is OK. Now, we need to understand the history of search engines, so we hope that there are two keywords on "Search Engine" and "History" on the webpage.
Example: Search all Chinese web search with keyword "search engine" and "history": "Search Engine History" results: Chinese (Simplified) webpage for search engine history has been searched. There are about 78,600 query results, which is 1-10. Search for 0.36 seconds.
With two keywords, the results of the query have been reduced from more than 70,000 items. However, check the search results, find that most of the results in the forefront still do not meet the requirements, most of the "history" involved in the web page is not what we need "Search Engine". How to do it? Delete "history" that is not related to the search engine. We found that this part of the useful information is always related to "culture", and some common words are "Chinese history", "world history", "historical books".
6.2, search results requirements do not include certain specific information
Google uses a minus "-" to represent the logic "non" operation. "A -b" means searching for a web page containing A but no B.
Example: Search all Chinese web search with "Search Engine" and "History" but does not include "culture", "Chinese history" and "world history": "Search Engine history - Culture - China History - World History" results: Search for search engine history - culture - Chinese history - world history Chinese (Simplified) webpage. There are about 36,800 query results, which is 1-10. Search for 0.22 seconds.
We see that the search results have been reduced by nearly half by removing disrelated information. The first search result is:
Search engine-through train ≡ Search engine development history search engine traffic, ... search engine professional introduction site. ... www.se-express.com/about/about.htm - 14k - Web Snapshot - Similar web
Very compliant with search requirements. In addition, the eighth search results:
463 Search Wang Ben Station Retrieves the entire website to enter keywords here. Your current location: Home >> Internet Search Handbook >> The history of the search engine. ... www.cnco.net/search/history.htm - 21k - Web Page Snapshot - Similar web
Also in line with search requirements. However, 10 results have only two meetings, and there is not too little. However, before you don't have a better strategy, you may wish to open a result. Pinbook's page named "Search Engine Development History", we found that the history of search engines is closely related to the earlier file search tool "Archie". In addition, the search engine seems to have a core program called "spider", and the earliest forming search engine is "lycos", making the search engine deep into the hearts of "Yahoo". Understand this information, we can further allow the search results to meet the requirements.
Note: "" and "-" here are English characters, not " " and "-" of Chinese characters. In addition, between the operator and the keyword, there is no space. For example, "Search Engine - Culture", the search engine will be deemed as the keyword "Search Engine" and "Culture" logic "and" operation "-" ignored.
6.3, the search results include at least one of the plurality of keywords to represent the "OR" representation logic "or" operation. Search for "a or b", means saying, searchable, either, either B, or there are A and B. In the above example, we hope that the search results contain one or several of the keywords such as "Archie", "Lycos", "Spider", which can be further streamlined.
Example: Searching for the following web page, you must contain "Search Engine" and "History", no "culture", you can contain any one or more people in the keyword: "Archie", "Spider", "Lycos", "Yahoo" ". Search: "Search Engine History Archie or Spider Or Lycos Or Yahoo - Culture" Results: Searched Search Engine History Archie or Spider Or Lycos Or Yahoo - Culture Chinese (Simplified) web page. There are about 8,400 query results, which is 1-10. Search for 0.16 seconds.
We see that the search results are reduced to more than 8,000, and most of the top 20 results are in line with search requirements. If you want to know the history of search engines, you may wish to study the results found now.
Note: "Continue" or "instead of lowercase" OR "instead of lowercase" OR "instead of lowercase.
In the above example, I introduced the most basic syntax of the search engine "and" Non "and" or ", these three search syntax google use" "(space)," - ", and" or ". On the way, you can also understand how to narrow the search range, quickly find the general method of the purpose of the purpose: the target information must contain the keyword ("connected), the target information cannot contain keywords (with" - "Remove), the target information may contain keywords (connect with" OR ").
