The Design And Implementation Of Information Search Module Based On A Knowledge Payment Platform

Knowledge payment refers to the reprocessing of knowledge to make it a knowledge commodity or knowledge service,so as to realize the commercial value that knowledge itself does not have.Knowledge payment platform produces,displays and sells a variety of knowledge commodities and knowledge services through a variety of devices,and provides social media functions for users in the learning process.With the rise of the concept of knowledge payment in recent years,how to design an information search module for a knowledge Payment platform with multiple devices,multiple commodity types which has attributes of both Payment and social media,so as to play an important role in user drainage and behavior data collection,is an important and challenging proposition.This thesis mainly describes the design and implementation of information search module based on a knowledge payment platform.The search module consists of several important sub-modules,such as data import,data synchronization,aggregate search,etc.This thesis first describes the conception of knowledge payment and circumstance of knowledge payment platform,following the project background of the search module.The thesis introduces the data storage technology and software development technology the project used,including Elastic Search,Redis and microservice architecture,etc.Then the thesis describes requirements of the search module,the analysis and designing of five important sub-modules,with core data structure and database table design.Finally,the implementation results of the important functions of the search module are described.The search module implemented in this thesis can provide search function with backend support for multiple devices of the knowledge payment platform.The system supports 20 commodity types and 7 social information,with good compatibility and scalability.
