使用
es 中? 的关键概念
索引：?类似关系型数据库中的表
文档：类似关系型数据库中 表的一条记录
创建索引
curl -H "Content-type:application/json" -XPUT http://127.0.0.1:9200/hotel -d '{"mappings":{"properties":{"title":{"type":"text"},"city":{"type":"keyword"},"price":{"type":"double"}}}}'
{"acknowledged":true,"shards_acknowledged":true,"index":"hotel"}
hotel 为 索引名称
创建文档 002 为id
curl -H "Content-type:application/json" -XPOST http://127.0.0.1:9200/hotel/_doc/002 -d '{"title":"希尔顿酒店","city":"深圳市","price":1999.99}'
curl -H "Content-type:application/json" -XPOST http://127.0.0.1:9200/hotel/_doc/007 -d '{"title":"希尔顿宾馆","city":"深圳市","price":79.99}'
curl -H "Content-type:application/json" -XPOST http://127.0.0.1:9200/hotel/_doc/001 -d '{"title":"天上人间","city":"深圳市","price":299.99}'
curl -H "Content-type:application/json" -XPOST http://127.0.0.1:9200/hotel/_doc/003 -d '{"title":"情侣酒店","city":"上海市","price":5999.99}'
搜索 id 为 001 的文档
curl http://127.0.0.1:9200/hotel/_doc/001
搜索 价格为 299.99的文档
curl -H "Content-type:application/json" -XPOST http://127.0.0.1:9200/hotel/_search -d '{"query":{ "term":{"price":{"value":299.99}}}}'
摸糊搜索 title 希 的文档
curl -H "Content-type:application/json" -XPOST http://127.0.0.1:9200/hotel/_search -d '{"query":{ "match":{"title":"希"}}}'
给合 kibana7.0.0
