elasticsearch-dsl 查询语法

python elasticsearch-dsl 查询

pip install elasticsearch-dsl
pip install elasticsearch

from elasticsearch import Elasticsearch
client = Elasticsearch('127.0.0.1:9021')

 def esSearch():
        from elasticsearch_dsl.search import Search, Q, A
        index = 'test_case_index'
        search = Search(using=client, index=index).params(size=10000)
        
        # 1.匹配条件
        q1= Q("match", project_id=581) & Q("match", is_delete=0)   # 等于
        q2 = Q("terms", id=[1, 3, 5, 7, 9])                        # in
        search = search.query(q1).query(q2)
        
        # 2.范围查询(range)
        search = search.filter("range", create_time={"gte": '2020-02-26T20:17:04.000Z', "lte": '2020-03-27T20:53:24.000Z'})
 
        # 3.排序
        search = search.sort({'create_time': {"order": "desc"}})
 
        # 4.返回结果过滤
        search = search.source(include=["id", "create_time"], exclude=[])
 
        # 5.求和 （无返回值）
        search.aggs.metric("sum_age", "stats", field="age")   # 对age求和; stats为固定字段名，可改为extended_stats
 
        # 6.分组求和 （无返回值）
        search.aggs.bucket("groupDate", "date_histogram", field="creation_time", interval="day", format="yyyy-MM-dd")   # 按照creation_date分天统计记录条数,相当于count(id) group by day
 
        # 7.执行
        search_result = search.execute()
 
        # 8.结果转化为dict
        search_result = search_result.to_dict()
 
        return search_result
