1、集群相关
--- 查询集群健康状态 GET _cluster/health--- 查询所有节点 GET _cat/nodes--- 查询索引及分片的分布 GET _cat/shards--- 查询所有插件 GET _cat/plugins
2、索引相关查询
--- 查询所有索引及容量 GET _cat/indices--- 查询索引映射结构 GET my_index/_mapping--- 查询所有索引映射结构 GET _all--- 查询所有的相同前缀索引 GET my-*/_search--- 查询所有索引模板 GET _template--- 查询具体索引模板 GET _template/my_template
3.索引的操作
1、写入索引模板
PUT _template/my_template{ "template" : "my-*", "order" : 0, "settings" : { "number_of_shards" : 10, "number_of_replicas" : 0 }, "mappings": { "default": { "_all": { "enabled": false }， "properties": { "name": { "type": "text" }, "age": { "type": "long" } } } }} 2、创建索引映射结构
PUT my_index{ "mappings": { "doc": { "properties": { "name": { "type": "text" }, "blob": { "type": "binary" } } } }} 3、写入索引
PUT my_index/doc/1{ "name": "Some binary blob", "blob": "U29tZSBiaW5hcnkgYmxvYg==" } 4、删除索引
DELETE my-index
5、DSL query查询
a、查询所有GET _search{ "query": { "match_all": {} }}b、查询单个索引 的 固定属性--- 精确匹配GET _search{ "query": { "term": { "name" : "you" } }}--- 模糊匹配GET _search{ "query": { "match": { "name" : "you" } }}--- 范围查找GET _search{ "query": { "range": { "age":{ "gte" : 15 , "lte" : 25 } } }}c、功能性查询--- 过滤GET my_index/_search{ "query": { "bool": { "filter": { "term":{"age":1095} } } }}--- 或 orGET my - test / _search {"query": {"bool": {"should": [{"term": {"name": "you"}}, {"match": {"age": 20}}]}}}--- 与 ANDGET my-test/_search{ "query": { "bool": { "must" : [{ "match" : { "name" : "you" } },{ "range":{ "age":{ "from" : 10 , "to" : 20 } } }] } }}---必须 =GET my_index/_search{ "query": { "bool": { "must" : { "range" : { "age" : { "from" : 10, "to" : 20 } } } } }}--- 必须不 notGET my_index/_search{ "query": { "bool": { "must_not" : { "term" : { "name" : "you" } } } }}d、复合查找GET my_index/_search {"query": {"bool": {"should": [{"match": {"age": 40}}, {"match": {"age": 20}}],"filter": { "match":{ "name":"you" }}}}}e、索引迁移--- 场景 从A索引 复制到B索引POST _reindex{ "source": { "index": "my_index" }, "dest": { "index": "new_my_index" }}f、基于查询的删除POST test-index/_delete_by_query{ "query":{ "term": { "cameraId":"00000000002" } }}--- 查询GET test-index/_search{ "query":{ "term": { "cameraId":"00000000002" } }}
