In order to obtain ideal information retrieval results, what factors should be considered when choosing a retrieval engine?

Google search engine is popular among netizens because of its accurate and fast search service, and has become an essential tool for them to query information. Google search engine itself does not live up to the expectations of netizens, and constantly introduces new search functions. In addition to the common retrieval functions such as site, inurl, intitle, various file types and link information, a series of new retrieval services have been launched recently. Generally speaking, these new retrieval functions are more humanized and closer to people's daily life and needs, so they are easily accessed by users.

1, Chinese pinyin input retrieval

In order to facilitate users who use Chinese to search online, Google allows users to input Chinese Pinyin directly on the keyboard to retrieve related things, such as:

Entering Shanghai Shi Kebiao

Search results prompt: Are you looking for: Shanghai timetable?

This is the key word we need to find, and users can browse related results according to it, including the timetables of various vehicles in Shanghai. If you need to find more detailed information "Shanghai Flight Timetable", just enter feijihangban in the middle of the original search result "Shanghai Timetable", for example: Shanghai feijihangban Timetable.

This new function of Google can prevent users from switching between Chinese and pinyin input. When users enter pinyin, don't leave spaces, otherwise Google will mistake English. Google has a one-to-one correspondence between pinyin and commonly used words or phrases, so words or phrases that are too uncommon are not suitable for searching in this way.

2. Chinese-English dictionary

Users who often use computers will naturally have one or two dictionary software at hand to find and translate Chinese and English words. As a common tool, Google also provides a Chinese-English dictionary which is very convenient to use. Users can find the word meaning according to the following methods: input fycomputer to find Chinese word meaning, and then input translation computer to find Chinese word meaning.

3, gas query

The weather is also one of the information that people often want to inquire about. The weather query provided by Google comes from an updated meteorological website in China, which is suitable for people in China. Users can query in Chinese and English. For example, to know the weather in Athens during the Olympic Games, you can enter it in the following ways:

In the query results returned by Athens Weather TQ, the first item will appear as "Athens Weather Forecast", and the user can see the weather situation in Athens that day after clicking it. If the place names are the same, users need to make another choice.

4. Stock inquiry

There are many websites for stock inquiry, but the stock inquiry provided by Google is just more convenient. Users can query according to the stock name, stock code or the initials of the stock name. The following is an example of querying the stock market of China Unicom.

China Unicom stock zglt gp

gp 600050

5, postal code and area code query

People often need to check postal codes and telephone area codes. Google provides such a practical function that users can obtain the name, postal code and long-distance telephone area code of the province and city they want to query. The following is an example query:

Postal code Hangzhou

Shaoxing area code

Yb Hangzhou

Qh Shaoxing

It should be noted that users can only query municipal postal codes and area codes, and cannot further query the specific information of districts and counties. 6, mobile phone attribution query

Users can get the number field, family, card type, postal code, telephone area code and other information after entering the mobile phone number, but from a practical point of view, only the mobile phone family information is more useful.

7. Use of calculator

Google has the function of calculator. For example, if you type 45*86+35/7 in the Google search box, you will get this result:

(45 * 86) + (35 / 7) = 3 875

Interested users, or users who often operate on the computer, might as well give it a try.

8. Shopping search

Google's new shopping search is called Froogle, and its website is/

As long as the user inputs the name of the commodity, he can see the picture and price of the commodity, and can also limit the price of a commodity to search, and list the search results from high to low as needed. Many goods can be ordered directly online, which is more popular with users.

9, the United States practical life information query

If users live in the United States or go to the United States for business and study for a short time, the following query function may help them again, because these search services are currently limited to the United States.

9. 1 area code query

Users enter the area code of the United States, and the first item in the returned search results is the map of this area. Users can find a specific street by clicking continuously.

9.2 Barcode query

Users can find the product description by entering the barcode of the product.

9.3 Aircraft flight inquiry

Users can enter the name and flight number of an airline, and get the departure and destination, departure and arrival time of the flight, as well as the actual sailing situation, check-in at present, and the house number of the arrival terminal.

9.4 License plate number inquiry

Users can get the name, model, factory year, body and engine of a car by inputting the license plate number.

9.5 mail inquiry

Users can know the current status of e-mail by entering the number of e-mail, such as whether the e-mail has arrived or is on the way.

10, search toolbar

Google's search toolbar has powerful functions, including drag-and-drop and right-click search functions, news reading, advertisement interception, website ranking display and search term labeling. The toolbar can be attached to the browser, which is more convenient to use. Users can download and install a search toolbar on Google website first, and then set it in toolbar options as needed. We recommend users to use this retrieval toolbar, which will bring many unexpected conveniences to users.

10. 1 Google News

Google's news comes from 4500 newspapers, magazines and news agencies. After being selected, continue to broadcast news from all over the world. Every news has an update time and is connected with related news. Users can use the free news notification service to receive news they are interested in by email.

10.2 website ranking

Google evaluates the importance of web pages by automatically calculating the structure of web links and many other variables. According to this evaluation, the website ranking can show the importance of the website that users are visiting, and it is displayed with a green line, which is intuitive and clear.

10.3 search term tag

Search term tags use bright colors to indicate the position of the words searched by users on each web page, which is convenient for users to view. Click the Search Word Tag button to turn tag status on and off.

10.4 drag-and-drop and right-click retrieval

Drag-and-drop retrieval function makes retrieval more convenient. Users can drag and drop the words selected on the web page directly into the search box, and Google will automatically search. You can also use this feature for text in many word processing applications running at the same time as a Web browser. Right-click retrieval means that users can select the text on the webpage, click the right mouse button, and then select "Google Search" in the pop-up menu for automatic retrieval.
