springboot+ solr 快速入门指南

Solr基于Lucene的Java搜索引擎服务器
Apache Lucene项目的开源企业搜索平台。其主要功能包括全文检索、命中标示、分面搜索、动态聚类、数据库集成，以及富文本（如Word、PDF）的处理。Solr是高度可扩展的，并提供了分布式搜索和索引复制。Solr是最流行的企业级搜索引擎，Solr4 还增加了NoSQL支持。

Solr安装配置
   1.下载Solr安装包
      wget https://downloads.apache.org/lucene/solr/8.5.2/solr-8.5.2.tgz

  2.创建常用软件目录及解压到指此目录
     mkdir -p /opt/software
      tar -zxvf solr-8.5.2.tgz

 3.创建自己的collection目录(例如collection1)
    mkdir -p /opt/software/solr-8.5.2/server/solr/collection1
    cp -r /opt/software/solr-8.5.2/server/solr/configsets/sample_techproducts_configs/conf /opt/software/solr-8.5.2/server/solr/collection1/

 4.运行solr
    cd /opt/software/solr-8.5.2/bin
    ./solr start -p 8983 -force

浏览器访问solr，地址为http://localhost:8983
​

添加core(选core admin,点击add core ,name、instanceDir都填写book

​

      下一步core selector下拉选择book添加自己需要的字段(例如:type 类型pint, create_time 类型string  publish_time string)

        ​
