Online information search technology more and more, how to efficiently and quickly find the answer to the problem? There are several techniques to make it easier to find the pages you need. No technology is omnipotent, but using a combination of several techniques can greatly speed up the web search process. Almost all popular search engines offer the ability to search by phrase, which is the best technique to search for pages in a vast web.
1. Phrase 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)".
As an example, a person looking for HP's Mpe/ix operating system's list of commands, he may only enter the word "Mpe/ix" in the AltaVista site, then he may find that there are 2,400 matching pages, if you fill in the search criteria, write "Mpe/ix" and " Commands "Two words are combined with and (logically), then the conditions may be 450 pages, and if you enter" Mpe/ix Commands "on the search criteria, only 15 records match, including the Iowa State University computing and Communications Management User's Guide, The MPE/IX system commands are described in detail
2. Phrase selection 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 simply typing a question as a phrase can work, especially on the AltaVista site, because it employs the "ask Jeeves" engine technology, which gives out-of-the-box answers to common problems.
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.
3. Clever use of error messages Searches all or part of the error message as a phrase. 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)." Entering the phrase at the Northern Light or HotBot site will find an explanation of the problem and how to handle it.
DejaNews and newsgroup documents often find it hard to even find answers through search engines. DejaNews newsgroup documents may be a faster source of information because newsgroups are more focused on discussions and Web pages are relatively less likely to change. Unfortunately, DejaNews cannot always handle the phrase engine adequately. Although it follows the usual syntax, its search engine is processor-intensive and often gives only partial results that match the search phrase. For this reason, it's a good idea to type a phrase without quotes on dejanews, and you want the record that contains the phrase to appear in the front. Some search engines are surprised when dealing with phrases--ignoring periods, searching for other forms of the word, omitting spaces, and so on--but not in the process of dejanews.
4. Directly to the information source to find Sometimes the phrase search is too precise or a phrase does not 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 site www.dell.com, and want to know what news Oracle has, try 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.
