When entering multiple words, Google defaults is to query, if you want to use or formulate queries, use or, for example: Java or C Google is not case sensitive, search Java and search Java or Java is complete the same. Logical relationship priority uses parentheses, such as looking up with Java and (JVM or virtual machine): Java (JVM or virtual machine). To search for phrases, you need to use quotation marks, such as searching Java virtual machines can be used: "Java Virtual Machine". To use a minus, such as search Java, such as searching, Java-training. Under normal circumstances, wildcards cannot be used, and wildcards can only be used in phrase, such as "using * mode". The specified content is searched only on the title of the web page (ie, the part specified by HTML Title), for example: INTITLE: JAVA. Search only within the URL of the web page, for example: InURL: Java. Search only in the text of the web page (ignore link text, title, and URL), for example: Intext: Java. Only in link text (link Java Research Organization link text is the search specified in the Java research organization), for example: Innchor: Java. Search only in the specified website, you can be a specific site or a domain classification, for example: site: javaresearch.org or site: ORG. Only search for specified content in the specified file format, you need to note that Google can only support limited common text formats, including rich text formats such as DOC, XSL, PPT, PDF, such as FileType: HTM. Google is sensitive to the order of the contents of the input when searching. If the result is not found, you can try to change the order of the keywords. When searching for multiple keywords, you can try to add quotation marks and do not quotation, and the results may have great differences, such as Java virtual machines and "Java virtual machines". Searching strategy can be used first, suppose you want to search for Java's Command mode, you can try Java Command Pattern, then try Java Pattern or Java Command, each reduced keyword should be you think One is not important. For search in Chinese, search "virtual machine" and search "virtual machine" are different, the latter is generally more than the former and the correlation is different, in general, you should add space between all words, There is no space in the word, so that the result is generally better. A keyword can be repeated twice, and the rankings and quantities of the result will also affect the results. It seems that there is no impact twice, such as search "Internet" and search "Internet Internet". Search content can only contain ten words, including options such as Intitle, and multiple parts are ignored. For INTITLE, INURL, INTEXT, INACHOR and SITE, do not use multiple times, otherwise it is not the result you want, or there is no result at all, mixing these options is legal, but the rules are very complicated.
