摘　　要：随着信息量的骤增,传统关系型数据库很难做到实时高效地检索用户需要的信息,并且无法对信息进行分词及关键词组合的短文本搜索,从而很难优化信息检索结果的推荐展示。针对大量信息频繁检索的问题,采取一种基于ElasticSearch分布式搜索引擎,并采用分词器和倒排索引等技术,能较好地解决这些问题。同时在研究过程中利用代码实现了基础功能搜索、地理位置搜索以及通过算分排序推荐展示等功能。With the rapid increase in the amount of information,it is difficult for traditional relational databases to achieve real-time and efficient retrieval of the information users need,and conduct short text search on information segmentation and keyword combinations,which also makes it a thorny problem to optimize the recommended display of information retrieval results.In light of this,this paper uses a distributed search engine based on ElasticSearch,and adopts technologies such as word segmentation and inverted indexing to better solve the problem of frequent retrieval of large amounts of information.At the same time,during the research process,it also introduces code to realize basic function search and geographic location search and carry out recommendation display through score sorting.
