The more specific the search criteria you give, the more accurate the search engine returns.

For example, if you want to find information about computer adventure games, it is useless to input game. Computer game range is smaller, of course, it is best to typing computer adventure game, the results will be much more accurate.

Sometimes you can even ask a search engine a question, the accuracy of return results will make you have to admire the powerful search engine function.

Once, we would like to find information on the basis of IP address to determine the source of access, because of the knowledge that "IP addresses" search is not useful, coupled with the search conditions are more complex, can not be a single word or phrase query, so we simply entered the whole sentence in google search engine:

How to recognize a visit the from it IP address

As a result, the first link in the returned page is what we need. The site not only provides access to the source query based on IP, but also uses virtual reality (Reality) technology to identify the city on the map.

You can see that the search conditions are refined to greatly improve your search efficiency.

Because of the differences between Chinese and English in terms of word arrangement (English words and words are separated by spaces, but not in Chinese), the word-cutting becomes a big challenge for search engines. While the engine that supports Chinese search has done quite well in terms of word-cutting, it is not realistic to ask for perfection. Therefore, in the case of more search keywords, we suggest that the Chinese words should be separated by a space to avoid too many invalid searches. For example, check the information of Chinese computer adventure games, and enter "computer game adventure" instead of "Computer adventure game".
