Foreword
As a technical person, often encounter their own do not know or do not know something, this time you must use the search engine to search relevant information, of course, most people can not escape google, google content on many, how fast searching and filtering the information they want has become a problem. In fact, google advanced search provides a way, but a lot of people are not very clear, with a simple google search assistance command, you can make your search more effective, and here I Jiyuan coincidence to see a foreign Web site on google search commands more complete summary, finishing the translation follows the original address https://ahrefs.com/blog/google-advanced-search-operators/ .
Article 42 lists the original author google search assistance command, the whole network should be the most complete (including foreign sites), but in fact there is already a part of evolution because google search, or because the decline of certain products has become history, I deliberately marked out with a strikeout, this section we look like.
Direct Search
This is the most simple, is to search for keywords you want directly in google.
For example: xindoo
A multiple-choice (OR)
When you have multiple query keywords, but only to meet one of the key words when you can, or you can put all your keywords to link with a pipe symbol | can, studied computer students know, the pipeline Fu | with or meaning.
Note that, or you need to have content in multiple queries prior to the merger of a query, your search is intended to be spread out, so there may be less accurate search situation.
For example: Jobs or Gates , Jobs | Gates also possible
Multi-criteria query AND
If you want to query the contents of the need to meet a number of conditions, you can use and the conditions you want to query all together. and it is suitable for the query instruction accurate information. (In fact google is the default and queries, so you can not add and instructions).
For example: For example, I would like to know csdn President Jiang Tao micro-blog, called "Jiang Tao," a lot of people, so it is necessary constraints, then you can search for Jiang Tao and csdn and microblogging
Exclusion -
In many cases, the association between a high two things, for example, to basically think of Steve Jobs of Apple, but if you want to look up information not related to Steve Jobs and Apple, direct search, then you might turn a lot of pages can not be found you want, you can use this time to exclude command - a.
For example: Jobs -apple
Fuzzy matching *
The technical people should be very popular, and we've heard some new technology when not remember the full term, just remember some of these keywords, this time we can not know the part with an asterisk * instead.
For example: Two days ago we survey the whole track link frame when a colleague mentioned a framework called jaeger began jaeger spell I remember back ger, I found tracing * ger is very easy to search to
priority()
When you query logic more complex, such as the first to meet x, y one of the conditions, then y satisfies the condition, the actual time line of your condition is a priority, similar to the four priority operations, multiplication and division first count, re-count addition and subtraction. If you want to add and subtract before the election would have () use parentheses to change the priority here, too.
For example: (iPhone or iPad) and Apple
Price inquiry $
You can specify keyword prices, here it is KaTeX parse error: Expected group after ' _' at position 12:, but ¥ also possible. __ For example: To query 329 ipad, you can search ipad $ 329 __
Define the query define:
Google search engine has built a dictionary that contains a lot of words, things, concepts ...... definitions can define: Trigger
For example: define: Philosophy
Cache query cache:
You can view the current version of the site so that Google search engine maintained.
For example: Cache: apple.com
Specify the file type filetype:
The instructions are useful for document query, for example, I want to download a paper, I can specify the filetype: pdf, so the search engine lists only the pdf you can download website.
For example: gfs filetype: pdf
Designated website site:
site: instruction to limit the search URL content is located.
For example: For example, I wrote a blog about wrk introduced before, so you can directly search wrk site: xindoo.blog.csdn.net first wants.
Association related:
You can list your searches and related: behind the content associated with, if you want to search the pains and sorrows before the star A and star B, you can use A related: B.
For example: c ++ Related: the Java
Title query intitle:
It is simply that you want to query in the title.
For example: you suddenly want to imitate under shock body, looking for the next two essay learning intitle: shocked
Enhanced query title allintitle:
Very similar intitle: but matching requirements more stringent, will need all the match, so it is suitable to use when you know that a full title to inquire about their content.
For example: For example, I turned a couple of days ago an article "Why should you (from now on) to write blog," you want to find the original, so that you can search allintitle: Why You Should (from now on) to write blog
Link query inurl:
Link query, the query for a complete link when you only know part of the link.
For example: For example, someone made a half link, I'm looking for the full text, so you can search inurldetails / 104161776
allinurl:
Queries link enhanced version requires that all keywords are linked in
such as: inurl: CSDN the Details / 104 161 776

A little difficult to understand, I give an example, I made a website such as the above have Apple's official website buttons, but in fact the point is not to jump to Apple's official website, will jump to my blog blog.csdn.net/xindoo years, inanchor the index is Apple's official website several hyperlinked word, inurl is the index of hyperlinks.

For example: steve Jobs dateRange: 11278-13278
Forced match +
