Embodiment 1

[0030] A query method using index data files, the implementation process is as follows figure 1 shown, including the following steps:

[0031] 1) Load the index data file into memory;

[0032] 2) Load the pre-query result file into memory;

[0033] The pre-query result file contains the distribution of all product data on the specific value of each product attribute; through the pre-query result file, the specific value of each product attribute, product quantity information, and product list can be directly obtained Information; when product data changes, such as new products, it is necessary to regenerate the pre-query result file and update it to the memory at the same time;

[0034] 3) Construct a query matcher

[0035] The construction steps of the query matcher include: according to the number of product attributes, construct a matcher array, each element in the array is a matcher, each matcher corresponds to a product attribute, and the elements of the matcher array ...

Embodiment 2

[0044] Embodiment 2 is an implementation method of the present invention that utilizes the index data file query method to be specifically applied to mobile phone classification query. Wherein, the establishment of the index data file includes the following steps:

[0045] 1) Product attribute ID

[0046] There are many types of product attributes, including brand, system, system, main screen size, and special functions. In order to quickly compare product attributes, converting all product attribute values ​​into digital identification codes can significantly help quick retrieval, and the comparison between numbers is direct and fast.

[0047] The ways to convert product attributes into digital identification codes are as follows:

[0048] Convert the value of the brand into a digital ID, such as [Samsung, HTC, Apple, Huawei] → [9344, 3443, 5544, 4342];

[0049] Convert the value of the standard into an enumeration, for example [GSM,WCDMA,TD-CDMA,CDMA2000,LTE(4G)]→[1,2,3,4...

Abstract

The invention relates to a query method using an index data file. The query method using an index data file comprises the following steps of: 1) loading an index data file to a memory; 2) loading a pre-query result file to the memory; 3) constructing a query matcher; 4) selecting the matching data; and 5) inquiring about the matching, and recording the matching result. The method provided by the invention can quickly perform classification retrieval and statistics of products through query using the index data file.

Description

technical field [0001] The invention relates to the field of information query, in particular to a query method for classifying, retrieving and counting products based on query conditions and using index data files. Background technique [0002] An important function of the application of the product library is to classify the specified products and search according to different product attributes. It is convenient to see the differences between different products with the same attribute. Taking mobile phone products as an example, the common attributes of mobile phone products we usually see include brand, mobile phone system, smart operating system, main screen size, main screen parameters, CPU frequency, etc. When a netizen makes a query: the brand is Samsung, the operating system is Android4.1, and the screen size is larger than 4.3 inches. This search netizen usually hopes to get 2 results: a list of eligible products and the number of products. [0003] For the real...
