spring data elasticsearch多索引查询

一次查询多个索引数据

es里可以这样写

GET 索引1,索引2,索引3/_search

也可以这样

给索引创建别名，多个索引可以使用一个别名

POST /_aliases
{
  "actions": [
    {
      "add": {
        "index": "myindex2",
        "alias": "myalias"
      }
    },{
      "add": {
        "index": "myindex3",
        "alias": "myalias"
      }
    }
  ]
}

或者

PUT /myindex2/_alias/myalias 

删除别名

POST /_aliases
{    
  "actions": [        
    { 
      "remove": { 
        "index": "myindex3", 
        "alias": "my_index_alias" 
      }
    }    
  ]
}

 

java查询多个索引

SearchQuery searchQuery = new NativeSearchQueryBuilder()
                .withIndices("myindex2","myindex4")　　//可以直接使用别名
                .withQuery(queryBuilder)
                //.addAggregation(sumBuilder)
                .build();
        List
