Next article: The search in the website of the Business-to-consumer station one, continue to consider the following questions:

3, let the user search what content?

Obviously, the content of the general Web site is merchandise, plus some news bulletins and help articles. For platform-like sites, such as Taobao and Jingdong, because of the support store, the content also includes shops and brands. Although the content is simple, it is generally simple to do the content of the "search Partition", the purpose of the partition is not to let users in the same search results list both see the product display, and see the article and shop display.

Taobao Mall has two areas: goods and shops

1688 has three partitions: products, company and purchase information

Watercress default search is not divided into regions

said that, the current mainstream of the company's Web search content is only goods, brands or stores, such as the attributes of goods, search basic also do not partition.

When users search for goods, what components of the product do users often search for?

Here I put the user commonly used several search components are divided into 3 levels of importance: A, B, C;

Number

Component Name

Weight

1

Product Title

A

2

Brand (or manufacturer)

b

3

Classification

4

Various types of property specifications (such as color size, etc.)

5

Section number (or item number)

6

Product Details

1 The product title is the most common search component of the user and the most important component of memory. Most of the sites do not use Full-text search technology, is directly through the SQL statement fuzzy query product title keyword.

2 brand, classification and various types of attribute specifications, section number, which is often used by users of the second type of search, as a full-text search engine, these several components must be considered.

3 for product details, keywords, description and price components, if indexed, the search engine system requirements will be higher. It is estimated that only Taobao will consider the index of commodity details.

To determine the components to allow users to search, the search system will start to index these components, after the index is stored in the special index database, improve query efficiency. With indexing mechanism, the new speed and deletion speed of index should be considered well. Inconsistent index content and database content will disappoint users: the product on a new day can not be searched? Has the shelves per inventory been displayed on the front end so that users can search for them? These all need to be considered.

4. Next step

The search system has been indexed and users can start searching. After the user clicks the search, the retrieval system searches, analyzes and matches the index according to the key words, the middle process is too complex. Skip here, simply talk about the concepts of "recall" and "precision", and how to balance both in search in a Business-to-consumer station.

On the recall and precision of the interpretation, you can look at Baidu Encyclopedia of the simple explanation. The relationship between the two is reciprocal, which improves the recall ratio and the relative precision is decreasing. While improving the precision ratio, relative, recall is declining. For the Business-to-consumer, I have the following suggestions:

1 for SKU Less site, improve recall; On the contrary, many SKU sites, emphasis on improving precision.

2 in order to improve the recall, as much as possible to index commodity content components;

3 in order to improve the precision, the content components of some products do not support fuzzy search, such as Jingdong only support the accurate retrieval of commodity numbers, and do not support fuzzy search.

To be Continued ...
