We are confronted with an era of information explosion. As the New York Times laments, "information is no longer a scarce resource, and our attention becomes scarce." The advent and development of search engine technology makes it all easier. But we need to learn how to use search engines to find information and better search.

It has been said, "There are two kinds of knowledge, one is our own mastery of the problem, the other is that we know where to find the knowledge of a problem." "Search engines are becoming the largest information distribution platform in the history of human beings, and they provide great convenience for Internet users to information." We know that Wikipedia's definition of a search engine is a tool for finding information on the World Wide Web.

The current search engine interaction mode is mainly "keyword query + selective browsing" interactive mode. This interactive way is characterized by: users with a simple keyword as a query submitted to the search engine, the search engine is not directly to retrieve the target page feedback to the user, but feedback to the user a possible Search target page list, users browse the list and choose from the content to meet the needs of the information to browse.

We typically typed in the search box the keywords we thought could describe our intentions, defined the information we wanted, and looked forward to a page that was right there!

It is difficult for search engines to accurately understand the user's query intent through simple keywords, so you can only return the set of results that are likely to meet the user's needs as a list to the user, rather than providing the user with accurate retrieval of the target.

To get the desired search results more efficiently, we should be more "accurate" in articulating information needs. Or think about it: How will the Web creator of the same information needs describe it? or use the search engine's advanced search instructions to make the search engine more accurate in understanding our query requests.

L Strong join search, with double quotes (both Chinese and English quotes) before and after the search request to get the query search results that exactly match the search request.

L Exclude search, use the symbol "-" to operate to exclude specific words, so as to make more accurate search, use this instruction when the minus sign must be a space before the minus sign, followed by the need to exclude words.

L Search for pages from specific sites, use the "site:" prefix with site domain names to query pages from specific sites.

L Intitle and Allintitle, use "intitle:" prefix plus query words search page title contains query words page; use "Allintitle:" prefix with multiple groups of query words search Web pages with multiple sets of query words in title

L Inurl and Allinurl, use "inurl:" prefix plus query words search Web page URL contains query words page; use "Allinurl:" prefix with multiple groups of query words Search Web page URL containing multiple groups of query words

Commonly used advanced search instructions and others, the author is no longer listed here. These instructions can also be mixed to use, the combination of the use of variable, more powerful functions.

Search engine is one of the most complex computing systems in the world, it is powerful and unquestionable, but it has not reached the level of artificial intelligence and really understands the meaning and purpose of user search terms. We only have good use of search engines, so that it is more "smart" to work for us.
