Retrieval method, device and system

Abstract

The invention provides a searching method, device and system. Users need to select class information before searching, and due to the fact that all levels of categories and types of attributes of the same information are consistent in a preset data model, the obtained class information is the same when the different users select the same needed information in the data model, and the process is the process for standardizing the users to input key words. In addition, the class information selected by the users is the key words used by a server during searching, the key words are divided into different weights, the server carries out searching in sequence according to the weights of the key words from large to small to obtain screening information meeting all screening conditions, the server can carry out searching from the maximum range to the minimum range according to the distinguishing of the weights, and therefore the obtained result is more accurate.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a retrieval method, device and system. Background technique [0002] With the development of technology and the continuous improvement of informatization, we often retrieve the information we need through the website. With the continuous acceleration of the pace of life, we hope to obtain the required information faster and faster, but the existing information retrieval mostly uses The method of keyword matching display, such as: search engines such as Baidu and Google, need to manually enter the keywords of the things you need to search in the search bar when searching, but because different people have different knowledge levels or usage habits, in the search Sometimes the keywords input for the same thing may be different, so there may be many kinds of search results obtained, causing the searcher to screen and screen the search results multiple times, w...

[0002] With the development of technology and the continuous improvement of informatization, we often retrieve the information we need through the website. With the continuous acceleration of the pace of life, we hope to obtain the required information faster and faster, but the existing information retrieval mostly uses The method of keyword matching display, such as: search engines such as Baidu and Google, need to manually enter the keywords of the things you need to search in the search bar when searching, but because different people have different knowledge levels or usage habits, in the search The keywords entered for the same thing may be different at times, so there may be many kinds of search results obtained, causing the searcher to screen and screen the search results multiple times, which is labor-intensive

[0003] For example: different people want to check the price of Apple iphone5s, the first person enters the price of Apple, the second person enters iphone5s, the third person enters the latest price of Apple, etc., because the results obtained by the server for different keywords The difference is that the first person gets the input keywords and retrieves the search results, including the current price of fruit apples, the price of apple trees, the price of Apple mobile phones, etc., and various information about apple prices. The second kind of keywords are more specific and will The relevant information of iphone5s appears directly, including information such as price and sales situation, sales venue, etc. The third person enters the latest price of Apple and may get the latest price of various models such as iphone4, iphone4s, iphone5, and iphone5s, so different people search Due to the different input keywords of the same thing, the output results are very different
