es常用查询语句

1.注入es查询模板类

	// 使用注解 @RequiredArgsConstructor
    private final ElasticsearchRestTemplate elasticsearchRestTemplate;

2.查询示例代码

           long startTime = LocalDateTime.of(totalTime.toLocalDate().minusDays(1), LocalTime.MIN).toEpochSecond(ZoneOffset.of("+8"));
            long endTime = LocalDateTime.of(totalTime.toLocalDate().minusDays(1), LocalTime.MAX).toEpochSecond(ZoneOffset.of("+8"));

            RangeQueryBuilder filter = QueryBuilders.rangeQuery("sendTime");
            filter.gte(startTime);
            filter.lte(endTime);

            BoolQueryBuilder boolQuery = QueryBuilders.boolQuery();

            List list = new ArrayList<>(); 
            BoolQueryBuilder externalUserIdBuilder = QueryBuilders.boolQuery();
            for (String externalUserId : list) {
                externalUserIdBuilder.should(QueryBuilders.multiMatchQuery(externalUserId, "externalUserId", "event.externalUserId"));
            }
            boolQuery
                    .must(QueryBuilders.multiMatchQuery(dto.getOpenKfid(), "openKfId", "event.openKfId"))
                    .must(QueryBuilders.termsQuery("servicerGroupId", Lists.newArrayList(dto.getServicerGroupId(), 1L)))
                    .must(QueryBuilders.termQuery("origin", 3))
                    .must(externalUserIdBuilder);
            NativeSearchQueryBuilder query = new NativeSearchQueryBuilder();
            query.withQuery(boolQuery.filter(filter));
            query.withSort(SortBuilders.fieldSort("sendTime").order(SortOrder.ASC));
            SearchHits hits = elasticsearchRestTemplate.search(query.build(), KfMsg.class, IndexCoordinates.of("kf_msg_" + dto.getTenantId()));
            List> searchHits = hits.getSearchHits();
            log.info("查询的总条数是:{},es查询到的数据是：{}", searchHits.size(), searchHits);
            for (SearchHit hit : hits.getSearchHits()) {
                KfMsg msg = hit.getContent();
                log.info("查询到的信息是:{}", JSONObject.toJSONString(msg));
            }
            dto.setTotal(searchHits.size());
        }

3.es，kibnan查询示例
1.查询版本及mapping信息

// 查询版本信息
GET /
// 查询索引mapping信息
GET /索引/_mapping

4.查询示例

GET /索引/_search
{
  "from": 0,
  "size": 20, 
  "query": {
    "bool": {
      "filter": {
        "range": {
          "sendTime": {
            "gte": 1640534400,
            "lte": 1640620800
          }
        }
      },
      "must": [
        {
          "query_string": {
            "query": "wkDkH9EAAAUHxB7SVz3275mcse1FqQuQ",
            "fields": [
              "openKfId"
            ]
          }
        },
        {
          "query_string": {
            "query": "wmDkH9EAAAySXzaU5lUSa1yYolRwuAyQ",
            "fields": [
              "externalUserId"
            ]
          }
        },
        {
          "query_string": {
            "query": "936",
            "fields": [
              "servicerGroupId"
            ]
          }
        }
      ]
    }
  },
  "sort": [
    {
      "sendTime": {
        "order": "asc"
      }
    }
  ]
}

5.查询注意事项
如果存入的字段设置为text,则不能使用term进行查询，需要使用match进行查询
如果为字段设置了别名，则查询时使用"字段.字段别名"进行匹配查询
