1. Use logical words to help find


larger search engines support the use of logical words for more complex search definitions, commonly used are: and (), or (or), not (no, some and not), and near (the proximity of two words), and the proper application of them can make the results very precise and, in addition, You can also use parentheses to combine search terms, such as in Http://www.liszt.con (Liszt) (music or Jazz) and edu) not ("Bill Morrissey" or Indiana).





2. Use double quotes for accurate lookup


If you are looking for a phrase or multiple characters, the best way to do that is to enclose them in double quotes, which results in the least and most accurate result. For example, enter "search engine" in the search box, which will result in fewer and better results than the input search engine. If you do not find any results in the above method, try removing the double quotes.





3. Use the plus minus sign to qualify to find


Many search engines support words that must be included in search results by using a plus sign (+) before the search term, with a minus sign (-) to limit the vocabulary that the search results cannot contain.





4. Targeted Search engine


the results of queries with different search engines are often very different because they are designed for a variety of purposes and development, such as Ejanews (http://www.dejanews.com) is dedicated to the Usenet search engine, Liszt (http://www.liszt.com) is for mailing lists, IRC and other search engines.





5. Progressive Refinement Method


According to the search engine classification layer by layer, this is very effective for some of the key words are not sure of the data query. Yahoo put all kinds of information on the internet sorted, divided very fine, there are leisure and sports, entertainment, health and medicine, art and humanities and many other categories, and there are each major category of links into a lot of small classes, layer by layer to enter the link, classification is more and more fine, from your goal is getting closer. Because they are linked form, so easy to use and simple, I do not have to say it.





6. Select query methods as required


If you need to quickly find some of the more relevant information, you can use the search function of the catalog search engine, such as the use of Yahoo (http://www.yahoo.com). If you want to compare the resource information of a system to one aspect, you can use the directory to find it at the first level. If you want to find the information is less popular, you should use a larger Full-text search engine to find, such as AltaVista (http://www.altavista.digital.com/) or HotBot (http://www.hotbot.com/).





7. Attention to detail


when querying on the Internet, if you can pay attention to a number of details, often can increase the accuracy of search results, such as many search engines are case-sensitive letter, so if you are searching for keywords such as people's names or place names, you should use their uppercase and lowercase letters correctly.





8. Use search engine features to find


different search engines have some proprietary features that you can use to make your queries less effective: For example, if you want to know about a recent post on a newsgroup, you can enter the ~G group name in the DejaNews lookup box, for example, "~g Comp.lang.java.programmer ".





9. Using multiple search engines


Multi-Search engine is a search agent site that can query multiple search engines with only one keyword input, such as Searchspaniel (http://www.searchspaniel.com/) can query more than 200 search engines at the same time.





10. Use options to define the query


More and more search engines are starting to offer more query options, which make it easy for people to construct more complex search patterns, make more accurate queries, and better control the display of query results.





11. Limit your search to specific areas as much as possible


For example: in Yahoo Chinese website, you are looking for computer-related knowledge, then you do not need to let search engine in leisure and sports, health and medicine, art and humanities and other categories to find. You can enter the "Computer and Internet" category, select "Retrieve the site under this directory." And then start the search.





12. Use more specific vocabulary


For example, do not "dress", and use "suit"; do not use "flower" and "Rose". But try to remove as many synonyms or synonyms as possible.





13. Specify the field where the keyword appears


in the keyword before adding T:, search engine will only be in the name of the site query, that is only displayed in the site name contains keywords in the site.


before the keyword plus u: the search engine will only be queried in the URL.





14. Limit the scope of the query

The stronger the ability to
scope limits, the more accurate it is to find the information needed. The type of scope restriction that the search engine provides generally has the classification scope, the geographical scope, the time range, the website type scope as well as other special scope. Some search engines offer a number of special limits, such as domain name suffixes (com, gov, org, etc.), file types (text, graphics, sounds, and so on). These range-limiting, implemented methods vary: some are by adding special characters to the keyword, and some through a pull-down menu.





15. Try to use less space


when inputting Chinese characters as keywords, do not append unnecessary spaces after Chinese characters, because the spaces will be considered special operators, and the function is the same. For example, you enter the keyword "Computer", then it will not be used as a complete word "computer" to query, because there are spaces in the middle, will be considered to need to find all the same "electric" "brain" two words of the document, this range is more than "computer" as the key words query results, More importantly, it deviates from its original meaning.





16. Modify the default search engine for IE browser


on the ie4.0/ie5.0 toolbar, click on the "Search" icon, IE will call the default search engine excite for you to retrieve. To change the default search engine, you must alter the WIN98 registry. IE4.0 Modify the method is: Close IE, open Registry Editor, find [HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main], in the right pane double-click "Find", Enter the default search engine URL that you want to change, such as changing the default search engine to Google, and typing/google.


ie5.0/6.0 Modification method is: Open Registry Editor, find [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Search], In the right-hand pane, modify the contents of Customizesearch and SearchAssistant, and enter the default search engine URL to change.





17. Use phrase to speed up search


If only one word is searched, thousands or even millions of matching pages will be found. However, if you add another word, the search results will be more relevant. When searching, give two keywords, combine two words with and (logic), or precede each word with a plus sign, which greatly reduces the hit range and accelerates the search. Fortunately, all major search engines use the same syntax. A quoted phrase means that only pages that exactly match the phrase (including spaces) are the pages to search for. For example, in the search instructions, there is the phrase "this exact phrase (the exact phrase)", and the search engine only searches for pages that contain "this exact phrase (the exact phrase)".





18. How to use the phrase choice


generally in the web search engine, use phrase search to narrow the scope to find search results is the best way. However, using phrase search involves using a phrase to express a specific problem. Sometimes it works by simply typing a question as a phrase, especially on the AltaVista site because it employs the "ask Jeeves" engine technology, which gives out-of-the-box answers to frequently asked questions.


When you enter "Why is the sky blue" on the AltaVista, you will find the answer in the "Ask Jeeves" section and give a number of pages to answer the question. However, a simple and straightforward method of questioning works only for a subset of searches. Other phrases can also be used as search terms, especially if one of these phrases is unique or the phrase is a unique combination of several words. Try to search for names, product names, and even strings embedded in the program.





19. Clever use of error messages


searches all or part of the error message as a phrase. For example, when daylight saving time changes, Netscape Navigator (browser) generates an error message that contains the phrase "book marks have changed on disk (disc bookmark has changed)." If you enter this phrase at Google or HotBot site, you will find an explanation of the problem and how to handle it.





20. The most easily overlooked search method


Sometimes a phrase search is too precise or a phrase cannot accurately express the required information. Then you can go directly to the source of information, which is "simple as it seems," but it works. Do not use search engines, directly to provide some kind of information organization site. Many times we can use the formula "www. Company name. com" to guess the site of an organization. If not, then go to Yahoo, or use a search engine. For example, to find the instructions for Dell's existing attachment, go directly to the station www.dell.com, and want to know what news Oracle has, try a www.oracle.com, and then go to the news bar to have a look. People get a lot of useless information in search engines and forget to try the method. This technique can also be used for other search purposes and is not necessarily related to the company. Government agencies, professional associations and educational institutions can also provide good information resources. For demographic statistics, please go to www.census.gov and www.acm.org to see the list of recent meetings.





21. Find the author's name, organization name, or company name from the top or bottom of the page


If it is a personal page, then whether there is an author's profile, to see his education level, position, affiliation, etc. if it is an organization or company, whether there is a detailed introduction page, its history? What is the purpose of publishing this information? Have you ever heard of these individuals or units? Are you familiar with it? Is Credit good? This will help you to interpret the trustworthiness of the content of the page.





22. From the URL can get some clues to the site


For example: all with "~" symbol is the most personal homepage. From the suffix of the domain name can also get some clues:


Edu is an educational web site that may be a serious academic study or a student-made homepage.


. gov or. Gov.cn is a government web site, generally more authoritative and reliable, and will not publish inaccurate information randomly.


. com or. com.cn is the most common commercial website. When you introduce your product, you tend to exaggerate it, so be aware of the "critical" acceptance.


. NET network services, providing services to commercial or individual users.


. org is generally a non-profit organization whose views may be biased.





23. Click on the home page of the site to see the relevant information about the organization


If the page does not have a link to its homepage, you can directly access the address of the front of the domain name, which is often the homepage of the site. such as:/google/archives/000011.html this URL, you only need to address the "/archives" after all the letters are deleted, leaving only the/google on the line.
