非空匹配
返回在原始欄位中至少有一個非空值的文件：
比如下面的欄位都因為有值而被匹配
{ "user": "jane" }
{ "user": "" } ①
{ "user": "-" } ②
{ "user": ["jane"] }
{ "user": ["jane", null ] } ③demo比如：匹配所有ownerId 的值
{ "query": { "bool": { "must": [ { "term": { "businessId": "10" } }, { "exists" : { "field" : "ownerId" } } ], "should": [], "filter": [] } }, "from": 0, "size": 10, "sort": [] }
返回值：看ownerId
{ "took": 79, "timed_out": false, "_shards": { "total": 5, "successful": 5, "skipped": 0, "failed": 0 }, "hits": { "total": 2977535, "max_score": 2, "hits": [ { "_index": "csc-pacific-case-monitor", "_type": "case-monitor", "_id": "36501315", "_score": 2, "_source": { "caseId": "36501315", "addTime": 1537100564000, "caseTypeId": "776", "closerId": "17821", "closeTime": 1537100564000, "contactNumber": "[\"\",\"17764105080\"]", "content": "無人接單", "creatorId": "17821", "customerId": "115962670", "customerType": "1001", "deadline": 1537102364000, "feedbackTime": null, "businessId": "10", "businessName": null, "fourthCategoryId": null, "fifthCategoryId": null, "ownerId": "17821", "managerId": "17821", "questionId": "9984", "questionReasonId": null, "orderTypeId": "8", "source": "2", "statusId": "2", "subSource": "-1", "questionTypeId": "2767", "updateTime": 1537100564000, "startTime": 1537100564000, "priorityId": "7", "updaterId": "17821", "memo": null, "flowId": "533", "nodeId": "67266", "lifeCycle": "1", "latest_main_scn": 4900984951192, "latest_main_es_update_time": 1537100564740, "level_1": "1", "level_2": "3", "level_3": "6", "level_4": "11", "level_5": "621", "level_6": "622", "departmentId": 622 } } ] } }

空值匹配
這些文件將不會被上面的查詢匹配到：
|
|
①這個欄位沒有任何值。
②至少需要一個 non-null 非空值。
③ user 欄位完全丟失。
下面的demo，是匹配了上面的情況
{ "query": { "bool": { "must": [ { "term": { "businessId": "10" } } ], "must_not": [ { "exists" : { "field" : "ownerId" } } ], "should": [], "filter": [] } }, "from": 0, "size": 10, "sort": [] }
返回結果如下

"timed_out": false,

"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
