ElasticSearch7.6.2中语法使用(更新中)

1、统计loginName去重后的数量

GET /login_user_info/_search
{
"size":0,
"query":{"bool":{"filter":[{"terms":{"systemCd.keyword":["AAAAA"]}},
{"query_string":{"default_field":"userTypeCd.keyword","query":"2"}}],"adjust_pure_negative":true,"boost":1.0}},
"track_total_hits":2147483647,
"aggregations":{"userNum":{"cardinality":{"field":"loginName.keyword"}}}
}

2、将customer的值替换为loginName的值

POST login_user_info/_update_by_query
{
    "query":{"bool":{"filter":[{"query_string":{"default_field":"systemCd.keyword","query":"AAAAA"}},
    {"query_string":{"default_field":"userTypeCd.keyword","query":"2"}}],"adjust_pure_negative":true,"boost":1.0}},
    "script":{"inline": "ctx._source['customer'] = ctx._source['loginName']"},
    "track_total_hits":2147483647
}

3、时间范围查询

GET /login_user_info/_search
{
"query":{"bool":{"filter":[{"range":{"createTime":{"from":"2020-09-01T00:00:00.000Z","to":"2020-10-31T23:59:59.000Z",
        "include_lower":true,"include_upper":true,"boost":1.0}}}],
        "adjust_pure_negative":true,"boost":1.0}},
"track_total_hits":2147483647
}

4、异步多线程删除数据

# wait_for_completion=false : 开启异步
# scroll_size=2000 : 删除文档数
# slices=2 : 线程数量
# conflicts=proceed : 冲突继续执行

POST login_user_info/_delete_by_query?wait_for_completion=false&conflicts=proceed&scroll_size=10000&slices=10
{"query":{"bool":{"filter":[{"range":{"createTime":{"from":"2020-09-01T00:00:00.000Z",
"to":"2020-10-31T23:59:59.000Z","include_lower":true,"include_upper":true,"boost":1.0}}}],"adjust_pure_negative":true,"boost":1.0}},"track_total_hits":2147483647}

 5、计算user索引下每个systemCd下的文档数量, 请求语法

GET user/_search
{
    "size": 0,  
    "from": 20, 
    "aggs": {
        "group_by_tags": {    
            "terms": {
                "field": "systemCd.keyword"
            }
        }
    },"track_total_hits":2147483647
}
