How do most people use search engines?

How did it turn out?

When you look up a concept, you often find a bunch of useless content, which is time-consuming and laborious, but it goes hand in hand, such as when you are looking for a yellow site. This is even more obvious when we are looking for something professional.

This is the information explosion-the garbage information explosion brings us the predicament. But we always need high-quality information to solve the problem.

Moreover, the resources on the Internet, who can find higher quality content more quickly, undoubtedly have obvious advantages.

So, we all need advanced search engine skills.

In recent years, Black Baidu has almost become a “politically correct” thing. But why Baidu will be hacked, do not need to say more. The key to using Google, is the quality of its content-you can find what you want faster, and the quality of the content is higher.

Of course, there is nothing absolute, Baidu can not be inferior to Google, everywhere, such as localization, gossip, SEO enthusiasm. So if you don’t have a clue, you might as well look it up a few more.

There are a few more points to note with Google:

a. Use this URL: instead of “ncr” means that no country redirection, will not be connected to places such as Hong Kong / Japan.

b. Google academic use of this Web site:

c. Use English keyword search more often. On the one hand, Google is obviously better at dealing with English; on the other hand, a lot of English content is indeed better than Chinese content. can not speak English? Take your time.

Search engine has been born for many years, but also accumulated a lot of content, so a lot of simple questions, there are ready-made answers, at this time can directly search for answers.

But for more professional content, the effect of direct questioning is much worse. For example, you want to know a slightly more complex question: a professional report on dog smell.

At this point, if you search directly: a professional report on the dog’s sense of smell. You’ll get the result:

Do you see the difference?

This is just a simple example, if you want to search for more complex problems, you need a more complex combination, the effect of asking questions directly will be very poor, because the search engine is not so intelligent, its existing working principle, will be word segmentation, to stop the word and so on.

Advanced search instructions are not difficult to learn, because there are ready-made graphical interface instructions next to search engines, and the use of instructions is just faster.

a. For example, Baidu, in the settings in the upper right corner of the Baidu page to find “advanced search”, click, there is an advanced search graphical interface (as shown below), which basically includes all Baidu’s advanced search instructions.

b. For example, Google, finds “Advanced search / advanced search” in its settings, and when clicked, there is an advanced search graphical interface (see figure below), which basically includes the commonly used advanced search instructions.

Google even provides a Web site for practicing search skills: has other advanced search instructions in this site.

For example, use a few more search engines, search a few more keywords and so on.

Here are some instructions that you may use.

This is our most common use. All spaces are understood as plus signs, that is, the relationship with. For example, enter a big date, articles with both big and date, but not necessarily a big date. Moreover, some particularly commonly used words are often ignored, which is caused by the “to stop words” in how search engines work.

Format: keyword 1 OR keyword 2. Or, that is, to return the result of keyword 1, or to return the result of keyword 2.

Note: OR is uppercase, Baidu uses “|”.

Returns a page that does not contain keywords after the minus sign. Format: the minus sign is preceded by a space, and there is no space after the minus sign.

Minus the sign is very useful. For example, you search 100 degrees of content, there is a lot of Baidu’s own content-Baidu know, Baidu encyclopedia, Baidu library, Baidu experience. At this point, you can use a minus sign.

The above three instructions correspond to “with or not”.

Perfect matching search, matching content: including the order of keywords entered and keywords.

When you explicitly want to know something, you can use double quotation marks.

The wildcard (wildcard character), can represent any text.

For example: Zhou * Lun, will return to Zhou Jielun, Zhou Xilun, Zhou Yilun and other results. This instruction can be used when you are not sure about certain content, or when you need to search for related content.

Note: Baidu does not support this instruction.

Used to search for a specific file format. For example: filetype:pdf Jay Chou, you will find the pdf file about Jay Chou.

This function is very good, for example, if you want to download “The Demi-Gods & Semi-Devils” e-book, you can search filetype:txt The Demi-Gods & Semi-Devils. If you want to find some professional reports, you can search filetype:pdf or something.

Note: the file format supported by Google is much more than Baidu, and the specific self-examination.

Used to search for all files under a domain name, or subdomain names.

This feature is also useful. For example, you want to see Zhihu on the “how to lose weight” answer, you can search: how to lose weight, found the results are Zhihu.

Returns the result of a range of values that can be time, price, year, distance, and so on. For example: presidents 1991. 1995, is the search for 1991 / 1995 presidents.

Note: Baidu does not support this instruction.

Add the wave number to a keyword, you can tell the search engine: in addition to searching for a given keyword, but also search for words related to the keyword after the wave number. But actually used, did not find such an effect, including Google, Baidu. Moreover, it is not seen in both advanced searches, so it is only for reference.

Returns the meaning of the queried word. For example,: define capture, returns an explanation of capture, and the explanation is comprehensive, including its etymology, translation, frequency of use, and so on.

As an English user, I think this function is very good. In addition to convenience, I can also see etymology and frequency in it.

Note: Baidu does not support this instruction. Moreover, the quality of Baidu’s translation results is much worse.

Used to search for pages that contain keywords in the page title.

Note: this title is the title in search engine search results, not necessarily the title of the article-many times the two coincide, but not necessarily. If the two coincide, the content of this page is strongly related to this keyword, so you can use it.

For SEO personnel, this is also a way to investigate whether competitive sites have the intention to do SEO-if title is not optimized, it is clear that there is no rival.

The search returns files that contain multiple sets of keywords in the title of the page. For example, allintitle: Zhou Jielun Jay Chou, will find that the title contains both Zhou Jielun and Jay Chou content.

Used to search for keywords that appear in URL, supporting Chinese and English. For example: inurl:jingzhi. You will find the page that contains jingzhi in url.

If you want to find some kind of website, such as a government website, you can use inurl:gov.

Note: Baidu only supports English and does not support Chinese, perhaps because there are fewer Chinese in URL.

Similar to the allintitle: instruction.

Insert info:, before the corresponding web site for details of the site.

When searching for more complex issues, you need to use these instructions in combination. This has to be familiar with, you can use the URL mentioned above to practice:

For example:

For example, a “professional report on dog smell” mentioned above can be used as a key word: filetype:pdf * dog smell

To search for “find a professional report on dog smell on an organization’s website,” you can use this keyword: filetype:pdf * dog smell inurl:org
