Baidu Advanced Search

Professional Document Search Many valuable materials are not common web pages on the Internet, but exist in word, PowerPoint, PDF, and other formats. Baidu supports full-text searches for office documents (including Word, Excel, and PowerPoint), Adobe PDF documents, and RTF documents. To search for such documents, it is very easy to add a "filetype:" document type limit after a common query term. "Filetype:" can be followed by the following file formats: Doc, xls, PPT, PDF, RTF, and all. All indicates searching all these file types. For example, look for Zhang Wuchang's Economic Papers on transaction fees. "Transaction fee Zhang Wuchang filetype: Doc. Click the result title to download the document directly. You can also click "html version" after the title to quickly view the webpage content of the document. You can also use the professional document search function directly through the Baidu document search interface (http://file.baidu.com. Back to Top Stock, train schedule, and flight Query Enter the stock code, train number, or flight number in the baidu search box to obtain the relevant information. For example, enter the deep development stock code "000001", and the top of the search results will show the real-time stock market of the deep development. You can also perform the preceding query in Baidu's common search. Back to Top Advanced Search syntax Restrict the search scope to the webpage title -- intitle The webpage title is usually summarized in outline form. Limiting the scope of the query content in the webpage title can sometimes achieve good results. You can use "intitle:" to retrieve the key part of the query content. For example, you can search for Lin Qingxia's photo as follows: Photo intitle: Lin Qingxia Note: there must be no space between intitle: And the keyword behind it. Restrict the search scope to a specific site -- site Sometimes, if you know that a site has something you need to find, you can limit the search scope to this site to improve query efficiency. The method of use is to add "site: site domain name" after the query content ". For example, if the download software from Skynet is good, you can query: MSN site: skycn.com. Note: do not include "http: //" for the domain name after "site:". In addition, do not include spaces between "site:" and "site name. Restrict the search scope to the URL link -- inurl Some information in the webpage URL often has some valuable meaning. Therefore, if you specify a limit on the URL of the search result, you can achieve good results. The implementation method is to use "inurl:", followed by the keyword that needs to appear in the URL. For example, if you want to learn how to use Photoshop, You can query: Photoshop inurl: jiqiao. In the above query string, "Photoshop" can appear anywhere on the webpage, while "jiqiao" must appear in the webpage URL. Note: inurl: syntax and the keyword that follows. Do not have spaces. Exact match-double quotation marks and book names If the entered query term is long, Baidu may split the query term in the search result after analysis. If you are not satisfied with this situation, you can try to prevent Baidu from splitting query words. This effect can be achieved by adding double quotation marks to the query words. For example, if you search for Shanghai University of Science and Technology without adding double quotation marks, the search results will be split and the results will not be very good. However, after adding double quotation marks, "Shanghai University of Science and Technology ", the results are all qualified. The book name is a special query syntax unique to Baidu. In other search engines, book names are ignored, while in Baidu, Chinese book names can be queried. The query word of the book name number has two special functions. One is that the book name number will appear in the search results, and the other is the content expanded by the book name number and will not be split. The book name is particularly effective in some situations. For example, you can search for movies or novels that are popular and commonly used. For example, if you do not add the book name number to the movie "Mobile Phone", in many cases, the communication tool-mobile phone is used. After adding the book name number, the results of mobile phone are all about movies. Requires that the search results contain no specific query words If you find that some types of webpages you do not want to see in the search results and contain specific keywords, use the minus sign syntax, you can remove all these webpages that contain specific keywords. For example, you may find many TV series webpages in the hope of searching for the heroes of the arms in terms of martial arts novels. Then you can query the TV series: Note that there must be a space between the first keyword and the minus sign. Otherwise, the minus sign is treated as a hyphen, And the minus sign syntax function is lost. There is no space between the minus sign and the next keyword. Back to Top Advanced Search and personalized settings If you are not familiar with Baidu's various query syntaxes, you can use Baidu's Integrated advanced search interface to easily perform various search queries. You can also change the default search settings of Baidu in the settings on the right of the search box, such as the settings prompted by the search box and the number of search results on each page.
