{
  "query": {
    "bool": {
      "must": [
        
        {
          "terms": {
            "general.uuid": [
              "cc5a0bcd-7dd5-471a-8ff4-560b88c2ee8e"
            ]
          }
        }
      ]
    }
  }
}

2. 查询字段是存在，字段中不存在某值

{
  "query": {
    "bool": {
      "must_not": [
        {
          "term": {
            "structVersion.keyword": "2"
          }
        }
      ],
      "filter": [
        {
          "exists": {
            "field": "manualAnchorPoint"
          }
        }
      ]
    }
  },
  "from": 0,
  "size": 40
}

3. Http api 请求（Id查询）

curl -XPOST -H 'Content-type':'application/json' 'http://127.0.0.1:9200/edu_epditembank_test/_search?pretty' -d '{"query":{"bool":{"must":[{"terms":{"general.uuid":["ca7868fb-bdb8-458c-acc4-15382c8dd7f5"]}}]}}}' > index.json

4. 解决es查询超过1w条时异常

4.1 Http请求设置

curl -XPUT http://127.0.0.1:9200/_settings -d '{ "index" : { "max_result_window" : 100000000}}

4.2 配置文件设置

修改集群配置config/elasticsearch.yml文件，增加如下配置：
max_result_window: 100000

                        "mongoid.keyword": {
                            "gt": "53c8a77c8090404ffcae0a10"
                        }

                }
            ]
        }
    },
    "from": 0,
    "size": 10,
    "sort": [
        {
            "mongoid": {
                "order": "asc"
            }
        }
    ],
    "aggs": {}
}

6. 分片延时同步

PUT /_all/_settings{  "settings": {    "index.unassigned.node_left.delayed_timeout": "30m"}}

7. 查询es segment 配置

http://127.0.0.1:9200/_cat/segments/edu_epditembank_question_2?v&h=shard,segment,size,size.memory

8. 新增字段mapping

8.1 head添加

put http://127.0.0.1:9200/edu_epditembank_paper/_mapping/type-resource/
{
  "properties": {
    "supplementaryCatalog": {
      "type": "keyword"
    }
  }
}

8.2 http请求添加

9. 副本集设置

curl -XPUT http://127.0.0.1:9200/edu_epditembank_paper/_settings -d '{ "index.number_of_replicas" :"1"}'

10. head启动命令

/data/third_party/elasticsearch-head-master/node_modules/grunt/bin
nohup ./grunt server &

11. 字段返回限制

{"query":{"bool":{"must":[{"range":{"anchorPoint.machine.confidence":{"gt":"0"}}}]}},"_source":{"includes":["general.uuid"],"excludes":[]}}
