我不明白为什么 ES 在过滤时将数组中的 _id 字段加倍。
curl -X GET "http://localhost:9200/pgep-development_broadcasts/broadcast/_search?pretty=true" -d '{"query":{"match_all":{}},"fields":["_id" , “标题”]}' { “接受”:7, “超时”:假, “_shards”:{ “总数”:5, “成功”:5, “失败”:0 }, “命中”:{ “总数”:1, “最大分数”:1.0, “命中”:[{ "_index" : "pgep-development_broadcasts", "_type" : "广播", "_id" : "50ed959dcc93282abc000062", “_score”:1.0, “字段”:{ “_id”:[“50ed959dcc93282abc000062”,“50ed959dcc93282abc000062”], "title" : "24 heures d'info" } }] } }
