6 skills in Google search

Although many of my friends know how to use search engines to search for information, the efficiency varies with everyone. The reason is whether they have mastered the required search skills and knowledge. Google, as the leader in search engines, is second to none regardless of its unique search technology or unparalleled search speed. As a result, Google has won the attention of countless netizens ". To help more Cainiao and beginners quickly learn more flexible search methods, I will share the search skills I have learned with you:
I. Use search engines as calculators
If someone tells you that you can use a search engine as a calculator, don't be surprised. This is a real thing. Recently, Google has provided users with an arithmetic calculator in its search service. You can enter an arithmetic expression (for example, "9*6-3") in the search box to obtain the answer. If Google Toolbar software is installed, you can directly type it in the corresponding location of the browser, saving time for accessing the Google homepage. In addition, this calculator can not only perform simple addition, subtraction, multiplication, division, but also handle common conversion and physical constants. Unfortunately, these functions only support numbers in English and cannot recognize Chinese characters. With this computing function, you do not need to find a calculator everywhere after accessing the Internet.
2. "OR" misunderstood"
"OR" indicates the logical "OR" in many search engines. It indicates the relationship between multiple search keywords. However, many netizens mistakenly think that Google does not support the "OR" logical operator. The reason is very simple: after using this logical operator, no corresponding result is displayed, but it is counterproductive. The reason is that the English case is not paid attention to during use. In general, the English case is ignored in Google, but "OR" is an exception. For example, enter "search engine or history" and "search engine OR history" respectively, and the number of results is completely different, the former requires that the web page contain both the "search engine" and "history" keywords, while the latter requires only one of them to meet the conditions, of course, the difference in the number of results is more prominent.
3. How to select a server
Google has many Image sites on the Internet, and thousands of servers are used for searching. But you can know that they have different update speeds for different languages, in addition, the update time of each server is also different. The update method is usually incremental, that is, update some servers first, and then complete updates later. In use I found that Google for Chinese language the fastest updated server is the following URL: http://www3.google.com, because when I use http://www.google.com without finding any results, the use of http://www3.google.com to search often has unexpected results, this situation in the search for some of the updates such as current news frequent content more effective. Therefore, we recommend that you update the Google homepage url in the bookmarks as soon as possible.
