The Design And Implementation Of Telecom Search Engine Based On Solr

With the development of communication technology and the wide application of big data,the data volume of telecom enterprises has grown rapidly.Using previous search techniques to search for information is slow and inefficient,which is like looking for a needle in a haystack.At the same time,due to business expansion,the search engine needs to be customized according to enterprise characteristics to meet the search needs of different user roles.Therefore,how to find information quickly and precisely and how to search individualized have become an urgent problem for telecom enterprises.In this thesis,the design scheme of enterprise search engine is proposed for telecom enterprises.According to the characteristics of heterogeneous telecom data,effective extraction and retrieval are carried out.Meanwhile,personalized customization application and configurable search are realized.This thesis is based on the specific needs of telecom business and has great application value.The main research work of this thesis includes:(1)Study the current situation of telecom enterprise search.According to the characteristics of heterogeneous telecom data and personalized requirements,the design objectives,design requirements and functional and non-functional requirements of the system are given.(2)Research and analyze the composition,retrieval theory and related technologies of enterprise search engine,carry out overall analysis,and give the overall structure,system framework and database logic structure of the system.The system is divided into four modules: data extraction,engine service,application interface and visualization system configuration.(3)Design and implement telecom search engine.In the data extraction module,the extraction program is designed and implemented for multiple data sources and data types,supporting data source increment and total extraction,hot word statistics,word library synchronization and other functions.In the engine service module,modify the open source Chinese classifier IKAnalyzer to compatible with a higher version of Solr used by the system,rewrite the Solr method to return the segmentation results or import the lexicon based on the response parameters.In the application interface module,six business interfaces are designed and implemented,and the engine services of business logic and Solr are separated to provide users.In the visual system configuration module,provide visual interface for system maintenance,parameter configuration and other daily work.(4)It is shown that that function and performance of the telecommunication search engine meet the search demand of the telecom enterprise and can provide more efficient search service for the telecommunication enterprise.
