There is a magic way to play with Google: Use skills for 19 tricks

1. When multiple words are input, Google performs a parallel query by default. If you want to use OR query, use OR, for example, java OR c ++.
2. google is case-insensitive. Search for Java is the same as search for JAVA or java.
3. Use parentheses for logical relationship priority, such as java and (JVM or virtual machine): Java (JVM or virtual machine ).
4. To search for phrases, enclose them in quotation marks. For example, you can search for a Java virtual machine: "Java virtual machine ".
5. If you want to exclude some results from the search results, you can use the minus sign. For example, you can use the java-training function to search for results that do not include training results.
6. Generally, wildcards cannot be used. Wildcards can only be used in phrases. For example, "use * Mode ".
7. Search for the specified content only in the webpage title (that is, the part specified by the html title), for example, intitle: java.
8. Search for the specified content only in the url of the webpage, for example, inurl: java.
9. Search for the specified content (ignore link text, title, and url) only in the body of the webpage, for example, intext: java.
10. Search for the specified content only in the link text (the link text of the linked Java research organization is the Java research organization), for example, inanchor: java.
11. Search for the specified content only within the specified website. It can be a specific website or a domain name category, for example, site: javaresearch.org OR site: org.
12. Search for the specified content only in the specified file format. Note that google can only support a limited number of common text formats, such as doc, xsl, and ppt, rich text formats such as pdf, such as filetype: htm.
13. google is sensitive to the order of input content during retrieval. If you cannot find a suitable result, try to change the search keyword order.
14. When searching for content composed of multiple keywords, you can try adding quotation marks or without quotation marks. The results may be very different, such as Java virtual machine and Java virtual machine ".
15. The search policy can be implemented first, then less. If you want to search for the Java command mode example, you can first try java command pattern and then try java pattern or java command, the keyword that is reduced each time should be less important to you.
16. For Chinese search, searching for "Virtual Machines" is different from searching for "virtual machines". The latter generally has more results than the former and has less relevance, in general, you should add spaces between words without spaces in the words. The result is generally better.
17. A keyword can be repeated twice, which also affects the ranking and quantity of the results. Repeated two or more times does not have any effect, for example, the search results for "internet" and "internet" are different.
18. The search content can contain a maximum of 10 words, including options such as intitle, and the excess is ignored.
19. Do not use any search options such as intitle, inurl, intext, inanchor, or site multiple times at a time. Otherwise, either it is not the desired result or there is no result at all, mixed use of these options is legal, but the rules are complex.
