Practical Tips for Search Engines

The search engine grammar is a very practical set of rules. If you use it well, you can get one step faster in searching for information, and quickly abandon useless results to find the information you need. In order to make it easier for everyone to practice better, here is a navigation that can use Google search: Google search navigation · Fuyeor live navigation

filetype: file format (limited file)

Filetype literally means the type of file, that is, to get a specific type of file, it is one of the most useful commands. For example, if we want to get some PPT documents about “Positive Definite Quadratic Form”, we can enter:

Positive Definite Quadratic Form

Similarly, you can use this syntax when looking for PDF books or novel books. For example, if we want to find PDF books about “Russian Language and Literature”, we can search like this:

Russian Language and Literature

This is a very practical rule. Sometimes you can use this rule to directly download some resources you need (such as PDF e-books, PPT courseware, etc.).

in addition, Common document format included:

  • Word documents: doc (old version) or docx (new version)
  • Excel document: xls (old version) or xlsx (new version)
  • PPT file: ppt (old version) or pptx (new version)
  • Design poster document: pub
  • Text document: txt, PDF document: pdf
  • flash file: swf

intext: Keywords (limited text)

Use a character in the body content of the webpage as a search condition. For example, enter [intext:fuyeor] in Google to search for all webpages that contain “fuyeor” in the body of the webpage.


Restricted keywords

The following rules can be used to qualify keywords:

+Keywords: restricted keywords

For example, we only want results about Fuyeor, but direct search may have other meaningful results, such as “buyer” “foyer”, then we search for [+Fuyeor] to get results that only contain Fuyeor, and nothing else is similar Keyword interference.

“Keywords”: Exact match search

Putting the word to be searched in double quotation marks represents an exact match search, that is to say, the page returned by the search result contains all the words that appear in the double quotation marks, and the order must match exactly. Common search engines support this command. For example, search: “wordskey” (the original word is keywords )


-Keywords: Exclude specific keywords

The minus sign means that the search does not include the word following the minus sign. When using this command, there must be a space before the minus sign, and there is no space after the minus sign, followed by the word that needs to be excluded. Common search engines support this command.

For example: Amazon Rainforest -wikipedia. What is returned is the result that contains the word “Amazon Rainforest” but does not contain the word “wikipedia”:

Restricted range

Restricted scope means searching only on specific websites or paths. Contains several important syntax:

site: domain keywords

The meaning is to search only pages containing keywords on this website. The site command contains two parts. When used alone, it searches all pages of the website including this domain name. It is one of the most popular commands used by website SEOer optimizers.

Use all means to search only pages containing keywords on this website, such as 长春花, which means to search all webpages containing the keyword ” 长春花” on the site whose domain name is

Search the Fuyeor website about 长春花 in Baidu

If we know that certain content comes from a certain website, using this command can greatly shorten the search time!

  • site: Do not need to carry the protocol name, such as http://, only the domain name.
  • Do not put a space between site: and the domain name, and the colon is in English format.
  • Do not bring www, because www is a second-level domain name, and websites generally have many subdomains, not limited to www
  • There is no order restriction, but there must be spaces between instructions!

Websites without www are concise and professional, such as Weibo, Russian Yandex search engine, Twitter and other big websites.

Because the www prefix actually loses its meaning more and more now. In the earliest days, network services were distinguished by second-level domain names, for example:

  • stands for World Wide Web service,
  • represents the file upload service (File Transfer Protocol, FTP),
  • represents the mailbox service.

But now, the default domain name generally only has the service of website, so there is no need to add the www prefix

All+in command

The All+in command means to include two keywords at the same time. For example, [intitle: keyword 1 and keyword 2] is the title (title) contains keyword 1, the page contains keyword 2, then [allintitle: keyword 1 Keyword 2] means that the title contains two keywords at the same time.

It can be seen that there are two results
There is only one item left, the title includes both “Fuyeor” and “红刺林投” page

Ps: The reason why “Fuyeor” is not displayed is because Google has rewritten and hides the title [Fuyeor Docs]. In fact, the title has this keyword.

inurl:keywords appear in the URL

Look for keywords on the website address. First of all, the URL is: Uniform Resource Locator, which is the address of a given unique resource on the Web. Popular understanding is what we often call “website address”. In this way, inurl can be understood: on the website (url).


This instruction can also avoid copycat websites, for example: [hiv] where .gov is a government-specific domain name, and it can be seen that the search results are all pages of the government’s official website, which are more authoritative.

intitle: Keywords appear in the title

The meaning of this command is: to search for web pages with keywords in the title, you can also use two keywords:

[Intitle: Keyword 1 and Keyword 2], which means to search for web pages that contain keyword 1 in the title (title) and keyword 2 in the web page.

For example: [红刺林投 intitle:Fuyeor] means “Fuyeor” appears in the search title, and a webpage of “红刺林投” appears in the webpage. Of course, the included ones are more in line with the requirements, so they rank first.

inanchor: Keywords appear in anchor text、

inanchor: Keywords, meaning to search for web pages that appear in anchor text. Among them, anchor text means that there are hyperlinks on keywords, for example:

Tutorials and solutions | Fuyeor Docs

The search results returned by this command do not necessarily include keywords, but the search keywords are included in the link text to these pages. For example, I often use webroam when I leave a message on other websites, and wobroam often points to, then search for [inanchor:webroam] to find the website as shown. This command can be used to find a lot of resources, because some websites will point to download pages.

SEO personnel often use the inanchor command to find a competitor for a certain keyword, because when these competitors do SEO, the anchor text of the external link points to his website, so they can know that the website is a competitor for this keyword.

? And * wildcard any content

Consistent with our usual habits, * represents a series of characters, and “?” represents a single character. If you need to search for some part of the content you are not completely sure, you can use this command. But now the search engine has searched * as the default (default value), so you don’t need to use it.

Microsoft*e5 -> Microsoft 365 e5

link:Website Link to the page of the website

It means to find the external link of a certain page. For example: https://aaa. com/fuyeor-docs.html There is a link to on this page, then the search for [] will show https://aaa. com/fuyeor-docs.html this page.
