7, miscellaneous syntax 7.1, wildcard problem Many search engines support wild symbols, such as "*" represent a series of characters, "?" Represents a single character. Google supports the wildcard support. It is currently only "*" to replace individual characters and contains "*" must use "". For example, "" Take * Governing the Country ", indicating the first four phrases" to ", the end of the" governing "," * "can be any character. 7.2, Keyword Size Write Google is the same as the result of the English character case, "god" and "god" searches. 7.3, searching the entire phrase or sentence Google keyword can be a word (there is no space in the middle) or a phrase (there are spaces in the middle). However, use a phrase to make a keyword, you must add English quotes, otherwise space will be treated as a "and" operator. Example: Search for English information about the first World War. Search: "World War I" Result: "World War I" has been searched to the Internet. There are about 937,000 query results, which is 1-10. Search for 0.06 seconds. 7.4, Search Engine Ignore characters and force search Google's English words that appear on some networks, such as "I", "COM", "WWW", etc., and some symbols such as "*", ".", Ignore the handling. Example: Search for some historical information about WWW origins. Search: "History of WWW" Results: The following words are too frequent, not included in the search: WWW. Searched Chinese (Simplified) webpage for WWW history Internet. There are about 75,100 query results, which is 1-10. Search for 0.22 seconds. We see, search for "Historical Internet", but the search engine will omit "WWW" and "". So the above search only searches for "history" and "Internet". This obviously does not meet the requirements. Here I am using the knowledge of the search engine word. When we search for the "WWW history", the search engine actually divides this phrase into three parts, "WWW", "" "and" history "to retrieve, this is the word of the search engine. So even if you enter a continuous "WWW history", the search engine still retrieves the phrase as three keywords. If you want to force the ignored keyword, you need to add a " " number in front of the keyword. Search: " WWW History Internet" Result: Historical Internet, which has been searched for WWW History Internet. There are about 25,000 query results in total, which is 1-10. Search for 0.05 seconds. Another way to force search is to cause the keyword described above in English. In the previous example "World War I", "I" is actually ignoring the word, but because the search engine enforces this specific phrase because the English double quotes are caused by English dual quotes. Search: "" "WWW History" Internet "Result: Searched to" History "Internet of WWW" Internet. There are about 7 query results in total, which is item 1-6. Search for 0.26 seconds. We see that this search is in fact using the "WWW's history" as a complete keyword. Obviously, the page containing such a specific phrase is not a lot, but each item is very in line with the requirements. Note: Most commonly used English symbols (such as question mark, number, comma, etc.) cannot be a search keyword, and it is not possible to strengthen. ■ 8, Advanced Search has discussed some of Google's most basic search syntax.
Usually, these simple search syntax can solve most of the problems. However, if you want more quickly and more accurately, you need to know more things. 8.1, to restrict "Site" to search for "Site" indicates that the search results are limited to a specific website or website channel, such as "www.sina.com.cn", "edu.sina.com", or a domain name Such as "com.cn", "COM", etc. If you want to exclude a website or domain name, you only need to use "- Website / Domain". Example: Search for a page about search engine skills on the Chinese Education Research Website (Edu.cn). Search: "Search Engine Skills Site: Edu.cn" Result: The Chinese (Simplified) page of Search Engine Skills Site: Edu.cn has been searched. There are about 608 query results, which is 1-10 items. Search for 0.05 seconds. Example: The famous IT portal ZDNET and CNET searches for information about search engine skills. Search: "Search Engine" Tips Site: www.zdnet.com "Result: Search in www.zdnet.com" Search Engine "Tips or Site: www.cnet.com There are about 1,040 query results. This is 1-10. Search for 0.09 seconds. Note that there is a small bug in Google here. "Search in www.zdnet.com ...", it should be expressed as " Search in www.zdnet.com and www.cnet.com ... "Search: Search for information about search engine skills in Sina Technology channel. Search:" Search Engine Skills Site: Tech.sina.com.cn "Result: The Chinese (Simplified) web page for search engine skills has been searched in Tech.Sina.com. There are about 163 query results. This is 1-10. Search 0.07 seconds. Note: The colon after Site is in English Character, and, there is no space after the colon, otherwise, "Site:" will be used as a keyword for a search. In addition, the site domain name cannot have an "http: //" prefix, and there is no "/" catalog suffix; Website channels are only limited to the "channel name. Domain name" mode, and cannot be a "domain name / channel name" mode. 8.2, find information "FileType:" in a class file "FileType:" is a very powerful and practical search syntax developed by Google. That is, Google can also search for some binary documents not only. Currently, Google already retrieves Microsoft's Office document such as .xls, .ppt, .doc, .rtf, WordPerfect document, Lotus1-2-3 Document, Adobe's.pdf Document, Shockwave .swf Document (Flash Animation), etc. These most practical document search is PDF search. PDF is an electronic document format developed by Adobe, and now has become an Internet Publishing standards. At present, Google's PDF document is about 25 million, about 80% of the number of binary documents of all indexes. PDF documents are usually some graphic and comprehensive documents, which are generally comprehensively comprehensively. Example: Search: "Assessment Table Filety: Doc or FileType: XLS OR FileType: PPT" Result: Searched Quality Bonds FileType: Doc or FileType: XLS or FileType: PPT Chinese ( Simplified network page.
There are about 481 query results, which is 1-10. Search for 0.04 seconds. Note that the downloaded Office file may contain macro viruses, cautiously. Example: Search for some PDF documentation on search engine knowledge and skills: "" Search Engine "Tips or Tutorial FileType: PDF" Result: Have to search "Search Engine" Tips or Tutorial FileType: PDF. 12,600 query results, this is 1-10 items. Search for 0.22 seconds. Let's look at one of the results: [PDF] Search Engines Tips Document Type: PDF / Adobe Acrobat - HTML version ... http://www.google.com/press/zeitgeist.html See What People Are Searching on at Google .com * Search Engine Watch.com/ Some Free Tips ... www.allvertical.com/promokits/searchenginetips.pdf - Similar web pages can be seen, Google uses [PDF] to mark this is a PDF Document retrieval, in addition, it also gives the HTML version of the PDF document, which retains the text content and structure of the document, but there is no picture. 8.3, the search keyword contains the first keyword in the "InURL" syntax in the URL link, which appears in the link or in the web document. There are many websites to display a certain type of resource names in the directory name or web name, such as "MP3", "gallary", etc., so you can find these related resource links with Inout syntax, then use the second Key words determine if there is a specific information. The biggest difference between InURL syntax and basic search syntax is that the former can usually provide very accurate topic. Example: Jeff Weiner. "The sea laughs". Search: "InURL: Midi" Bohai Laugh "" Result: The Chinese (Simplified) page of InURL: MIDI "Bohai" has been searched. There are about 27 query results, which is 1-10 items. Search for 0.34 seconds. Note: "InURL:" There is no space behind, and Google does not search for the URL symbol such as "/". For example, Google will use "/" in "cgi-bin / pHf" as a space processing. The link to the "allinURL" syntax returned to the page contains all the keywords. This query is only focused on the web page link string. Example: Find a company website that may have a PHF security vulnerability. Usually the CGI-bin directory of these websites contains a PHF script (this script is unsafe), which is "domain / cgi-bin / pHf" in the link. Search: "AllinURL:" CGI-BIN "PHF COM" Result: AllinURL has been searched to the Internet: "CGI-BIN" PHF COM. There are about 51 query results, which is 1-10. Search for 0.11 seconds. 8.4. Searching keywords are included in the web header "INTITLE" and "Allintitle" usage similar to the above INURL and ALINURL, just the latter query on the URL, and the former queries the web page title bar. The web page title is part of the HTML markup language Title. One principle of web design is to indicate the key content of the homepage in a simple language to the web header. Therefore, only the title bar is queried, and the high phase-related topic page can also be found.
Example: Jeff Weiner. Set of Japanese stars. Search: "INTITLE: Fujiwara Ji Xiang" Photo Album "Result: The Chinese (Simplified) page of the" Photo Collection "of Fujihara Jiku" Photo Album ". There are about 315 query results, which is 1-10. Search for 0.15 seconds. 8.5. The search for keywords are included in the "Anchor" chain in the "anchor", which is to quickly switch link points in the same page. Similar to URL and Title, Google offers two retrieves, "Inchor" and "AllinCnchor" for Anchor. This is not detailed.
