Intermediary transaction SEO diagnosis Taobao guest Cloud host technology Hall

The recent continuous research and analysis of large web sites, analysis of the best part, and absorb digestion, can be used as cleverly as possible to the company's website planning, today's homework is to study "Dangdang", I think we all should have to buy books experience it, a lot of E-commerce site imitation will start when, For example, our old opponents "art Dragon Net" early on when the information structure and functional design, I would like to say that Dangdang's search system.

This is Dangdang's search interface:

A very simple input box, said the user "what you want to find direct input keyword", is not the same as Baidu and Google, this is the highest level of search system, that is, a key to solve the best user experience, we together to uncover the secret behind this realm.

1. Full-Text Search

This function is the basic function, whether you enter the name of the book, or the name of the author, the publisher or the content of the book, you can search the results-full-text search, and can support the search of multiple keywords, and the query results according to the popularity of the book ranking, very convenient to help users accurately hit the expected results.

Search results will be keywords, highlighted to show, have to boast when the search speed, 2 seconds are not, really the best user experience-speed!

2. Multi-Condition Search

Commodity attributes are more, such as Price, classification, publication date, and so on, allowing users to query through a variety of conditions, and a variety of property values sorted output results. We allow users to query through multiple keyword queries, or to specify the classification of the query, the results of the query can be from high to low prices, from low to high, the publication date Ascending, the publication date in descending order and according to the best matching rules output search results.

Each sort of way, is in a certain kind of scene often use, also very fitting user's use habit, very fitting user language!

3, automatic removal of duplicate records

In the Full-text search, because of the large amount of data, there are often duplicate records. In order to improve the user's perception, the planners will never allow the same product to appear two times in the result, so the search system should have the function of filtering the duplicate records.

4, pinyin search function

In order to reduce the user's confusion of switching input method, Dangdang also provides the way of pinyin search, user-friendly, and according to the use of keywords to order the heat, respectively, display and display the expected search results, very powerful.

In addition to the key pinyin search, when not to do the Chinese title of the reminder, this I am very confused, why not do it? So that users only click on the link, you can travel to search, so that users have the most direct three effects:

1 looks like I found the right place.

2 Maybe I'm looking for something else?

3) Yes, I can make a few more words:

Do not know when why not do, really very sorry ....

5. Key-Correcting function

If the user enters a Chinese error, the system will automatically remind so the user experience and interactive effect is really good, such as you enter "Wei Qi", the system will automatically remind you "you may want to search: Welch", so that greatly improve the user's search results satisfaction, help customers to correct errors together.

6, Related words search function

One of the main tasks of the product search system is to help potential users to complete their shopping activities. Through the same meaning words of the reminder function, to provide users with more choices, thereby increasing the chance to complete the shopping behavior.

After the user search through the keyword, the system will prompt the relevant keywords, users can directly click to query the relevant content. For example, users search "planning" this keyword, the system will automatically prompt users a lot of relevant keywords "book China | Side Flower | Book Painting | Site Planning | Planning Group | Marketing planning "and so on.

7, search Results Classification summary function

Because the amount of data is very large, users can not only search by keyword, in order to help users, the search system will be based on the site's tag system, automatic search results by category automatically matching and emissions, to help users narrow the selection: such as input "planning" will be in the planning of the information displayed, For example, I know that the Web site planning books must be classified with computer science.

8. Search History Memory function

In order to more free users of the keyboard, Dangdang also provides a search memory, although the function is simple, but the design is still very necessary, it is worth learning, because users are very likely to repeat the search, because they need to contrast.

9, related search term statistics

This is the user does not know behind the story, after my survey found that the system daily users search the keyword summary, and calculate the most queries the word. These words are the most valuable reference to the site, through these words to analyze the most interesting content users, and according to the adjustment of the purchase, storage and sales strategy to create more benefits, so in Pinyin search can be sorted according to the heat.

10. Automatically update data

Dangdang's search system is not updated in time, such as the popularity of pinyin, because it will affect the speed of the search. In fact, the search system in our sleep, the system automatically updated, the next day we will be able to see the latest update results.

The above is my analysis of the summary, I hope to help you, hehe, the day before yesterday wrote "Nan: Do you know the label system of the website?" If everyone is interested, I will tidy up the "Nan: Do you know the search system of the website?" To help you make an in-depth analysis:
