我经过实际测试es5.2.2，发现_source/_all特性很好用： 1. _source可用通过配置includes、excludes获取应用需要的field "_source": {           "enabled": true,           "includes": [             "comId",             "name",             "userName",             "equips.name",             "equips.amount"           ],           "excludes": [             "phone",             "equips.code"           ]         }, 2.设置enabled=false关闭_source功能，关闭后，查询结果只返回doc的ID，而不会返回_source  "_source": {           "enabled": false, 3._all、include_in_all结合使用，是用户可用通过_all分词查询多个字段，而不需要写多个查询条件  "mappings": {       "testdoc03": {         "_all": {           "enabled": true         },         "_source": {           "enabled": false,           "includes": [             "comId",             "name",             "userName",             "equips.name",             "equips.amount"           ],           "excludes": [             "phone",             "equips.code"           ]         },         "properties": {           "comId": {             "type": "long"           },           "equips": {             "properties": {               "amount": {                 "type": "double",                 "include_in_all": true               },               "code": {                 "type": "text"               },               "name": {                 "type": "text",                 "include_in_all": true               }             }           },           "name": {             "type": "text",             "include_in_all": true           },           "phone": {             "type": "keyword"           },           "userName": {             "type": "text",             "include_in_all": true           }         }       }     }   }
