1、ES是如何实现分布式高并发全文检索
2、简单介绍ES分片Shards分片技术
3、为什么ES主分片对应的备分片不在同一台节点存放
4、索引的主分片定义好后为什么不能做修改
5、ES如何实现高可用容错方案
6、搭建Linux上环境三台ES高可用集群环境
7、基于ES网盘搜索引擎实现
网盘搜索引擎，写个Job 去网上爬虫 存储起来 以JSON的格式 存放在 ES服务器
网盘搜索引擎的原理：
采用ES存储抓取的数据 抓取服务器
测试数据：
##先创建索引 PUT /clouddisk ##测试数据maping POST /clouddisk/_mapping/disk { "disk":{ "properties":{ "name":{ "type":"text", "analyzer":"ik_smart", "search_analyzer":"ik_smart" }, "source":{ "type":"keyword" }, "describe":{ "type":"text", "analyzer":"ik_smart", "search_analyzer":"ik_smart" }, "shartime":{ "type":"date" }, "browsetimes":{ "type":"long" }, "filesize":{ "type":"float" }, "sharpeople":{ "type":"keyword" }, "collectiontime":{ "type":"date" }, "baiduaddres":{ "type":"keyword" } } } } POST /clouddisk/disk { "name": "2018史上最全美剧", "source": "百度云盘", "describe": "该课程由小明提供", "shartime": "2018-10-10", "browsetimes": 100000, "filesize": 4.35, "sharpeople": "美国东部", "collectiontime": "2018-11-24", "baiduaddres": "https://pan.baidu.com/s/1VQxFq6JnKh0KP-5aMq-WpA#list/path=%2F" } POST /clouddisk/disk { "name": "2018史上最全韩剧", "source": "百度云盘", "describe": "该课程小丽提供", "shartime": "2018-10-12", "browsetimes": 100000, "filesize": 6.35, "sharpeople": "韩国釜山", "collectiontime": "2018-11-24", "baiduaddres": "https://pan.baidu.com/s/1VQxFq6JnKh0KP-5aMq-WpA#list/path=%2F" } POST /clouddisk/disk { "name": "老友记", "source": "百度云盘", "describe": "该课程由张三提供", "shartime": "2018-10-10", "browsetimes": 100000, "filesize": 1.35, "sharpeople": "美国", "collectiontime": "2018-11-24", "baiduaddres": "https://pan.baidu.com/s/1VQxFq6JnKh0KP-5aMq-WpA#list/path=%2F" } POST /clouddisk/disk { "name": "英语雅思", "source": "百度云盘", "describe": "该课程由大海提供", "shartime": "2018-10-10", "browsetimes": 100000, "filesize": 1.35, "sharpeople": "大海", "collectiontime": "2018-11-24", "baiduaddres": "https://pan.baidu.com/s/1VQxFq6JnKh0KP-5aMq-WpA#list/path=%2F" } POST /clouddisk/disk { "name": "小猪佩奇", "source": "百度云盘", "describe": "该课程由朱佩琦出品", "shartime": "2018-10-10", "browsetimes": 100000, "filesize": 1.35, "sharpeople": "佩奇", "collectiontime": "2018-11-24", "baiduaddres": "https://pan.baidu.com/s/1VQxFq6JnKh0KP-5aMq-WpA#list/path=%2F" }
