语句
es查询的数据结构较简单时，数据示例如下：
"took" : 11,
"timed_out" : false,
"_shards" :
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
,
"hits" :
"total" : 1,
"max_score" : 0.0,
"hits" : [
"_index" : "my_index_name-20220614",
"_type" : "doc",
"_id" : "123",
"_score" : 0.0,
"_source" :
"qd_data" : "123456",
"date" : "20220614",
"enddatetime" : "2022-06-14 00:10:11.298",
"bizno" : "456789",
"requesttime" : "20220614000011522",
"@timestamp" : "2022-06-13T16:00:10.726Z",
"begindatetime" : "2022-06-14 00:00:10.726",
"jobid" : "1234567890",
"id" : "123",
"version" : "1",
"reqtsn" : "123456123456123456",
"sys_data" : "xyz"
]
查询语句
POST /my_index_name-20220615/doc/_search?
"query":
"bool":
"filter": [
[
"multi_match":
"type": "best_fields",
"query": "这里放查询的内容，例如：123456123456123456",
"lenient": true
]
],
"should": []
es查询的数据结构比较复杂时，数据示例如下：
"took" : 11,
"timed_out" : false,
"_shards" :
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
,
"hits" :
"total" : 1,
"max_score" : 0.0,
"hits" : [
"_index" : "my_index_name-20220614",
"_type" : "doc",
"_id" : "123",
"_score" : 0.0,
"_source" :
"qd_data" : [
"qd_remsg" : "",
"qd_params_sn" : "123456",
"qd_hostno" : "123",
"qd_haoshi" : "0.543",
"qd_sendparams" : "aaa",
"qd_rtimeout" : 3000,
"qd_ctimeout" : 2000,
"qd_jfflag" : "0",
"qd_endtime" : "2022-06-14 00:01:11.111",
"qd_resultcode" : "",
"qd_starttime" : "2022-06-14 00:01:10.222",
"qd_returncode" : "1",
"errcode" : "200",
"qd_requestsn" : "123456",
"qd_remsg" : "一致",
"qd_reno" : "123456",
"qdresult" : "MSG":"success","guid":"123456","RES":"1"
],
"date" : "20220614",
"enddatetime" : "2022-06-14 00:10:11.298",
"bizno" : "456789",
"requesttime" : "20220614000011511",
"@timestamp" : "2022-06-13T16:00:10.726Z",
"begindatetime" : "2022-06-14 00:00:10.726",
"sysreq_data":
"reqsn" : "123456",
"aaa" : "我是张三",
"bbb" : "2323",
"ccc" : "111",
"requesttime" : "20220614000010511"
,
"jobid" : "1234567890",
"id" : "123",
"version" : "1",
"requestsn" : "123456",
"sys_data" : "xyz"
]
查询语句：
POST /my_index_name-20220615/doc/_search?
"query":
"bool":
"filter": [
[
"multi_match":
"type": "best_fields",
"query": "sysreq_data=我是张三",
"lenient": true
]
],
"should": []
字段释义：
lenient：当查询报错时是否忽略该文档，默认为false
type: 定义内部查询方式和打分方式
| 值 | 描述 |
|---|---|
| best_fields | 按照match检索，所有字段单独计算得分并取最高分的field为最终_score，默认值，但不建议使用，数据量上来后查询性能会下降 |
| most_fields | 按照match检索，融合所有field得分为最终_score |
| cross_fields | 将fields中的所有字段融合成一个大字段进行match检索，此时要求所有字段使用相同分析器 |
| phrase | 按照match_phrase检索，默认slop为0，执行短语精确匹配，所以即便设置 minimum_should_match 也无效; 取最高字段得分 |
| phrase_prefix | 按照match_phrase_prefix检索，滑动步长slop默认为0；取最高字段得分 |
| bool_prefix | 按照match_bool_prefix检索 |
