The search engine provides great convenience for users to search for information. You only need to enter a few keywords. Any desired information will be collected to your computer from every corner of the world. However, if the operation is improper, the search efficiency will be greatly reduced. For example, if you want to query certain information, the search engine returns a large amount of irrelevant information. In this case, the responsibility is generally not in the search engine, but because you do not have the skills to improve the search accuracy. How can we improve the efficiency of information retrieval?
Search keyword training
No Doubt. Choosing the correct keyword is the beginning of everything. Learn to extract the most representative and indicative keywords from the complex search intent to improve information.
Query efficiency is crucial. Skills (or experience) in this area are the mother of all search techniques.
Refine search criteria
The more specific the search conditions are, the more accurate the results returned by the search engine. Sometimes the effects of inputting one or two keywords are completely different. This is one of the basic search techniques.
Use logical commands
Search logic commands generally refer to Boolean commands such as "AND", "OR", AND "NOT" AND the corresponding logical symbol commands such as "+" AND. Using these commands can also make our daily search applications get twice the result with half the effort.
Exact match search
Exact match is also a powerful tool to narrow the search result range. In addition, it can be used to perform search tasks that cannot be completed in other ways.
Special search commands
In addition to the general search functions, search engines provide some special search commands to meet the special needs of higher-level users. For example, you can query the external links pointing to a website and the functions of all related webpages on a website. Although these commands are not commonly used, they are useful when you need to search for them.
Additional search functions
Search engines provide some customized functions to facilitate user search. Common search methods include keyword search and restricted area search.
Search engine used
The search engine works in different ways, resulting in different information coverage. It is unwise for us to concentrate on only one search engine, because the best search engine also has limitations. A reasonable way is to select different engines according to specific requirements.
