Python操作Elasticsearch 几种查询

一些ES查询-DSL语法

wildcard模糊查询

# 真实车道进行模糊查询
crossroadName = "*" + roadName + "*"
# --1.通过道路名称查询cameraIdList
query1 = {"query": {"wildcard": {"crossroadName": crossroadName}}}

bool 布尔 + must 实现多字段联合查询

     query2 = {
        "query": {
            "bool": {
                "must": [
                    {"match": {"cameraId": i}},
                    {"match": {"cameraDirection": cameraDirection}}
                ]
            }
        }
    }

range 实现范围查询

gte : 大于等于
lte : 小于等于
gt  : 大于
lt  : 小于

query2 = {
        "query": {
            "bool": {
                "must": [
                    {"match": {"deviceIp": deviceIp}},
                    {"match": {"lane": lane}},
                    {"match": {"tailOrHead": 1}},
                    {"range": {
                        "passTime": {
                            "gte": startTime,
                            "lte": endTime,
                        }
                    }
                    }
                ]
            }
        }
    }
