由于您正在使用排序,因此您需要为要计算的分数显式设置“track_scores ”。

例:

{ 'size': 1,'query': { 'bool': {'must': [ { 'match': {'_all': {'query': 'test','operator': 'and','fuzziness': '2'}}}],'should': [ { 'multi_match' : { 'query': 'test' ,'type': 'best_fields' ,'fields': ['ObjectData.PRTNAME','ObjectData.EXTERNALID','ObjectData.contactList.VALUE','*SERIES','*NUMBER','ObjectData.INN'] ,'operator': 'or' ,'boost': 3 }}] } }, 'aggs': { 'byObjectID': { 'terms': {'field': 'ObjectID'}, 'aggs': {'latestVer': { 'top_hits': { 'sort': [{'creationDate': { 'order': 'desc' }}] ,'_source': { 'include': ['ObjectData.BRIEFNAME', 'creationDate', 'ObjectID' ]} ,'size': 1, ’track_scores' : 1 }} } } }}解决方法

我使用ES v 1.7。ES仅在“命中”部分返回_score,但是我对“命中”不感兴趣,我需要 使用_score 从响应的“聚合”部分中获取数据 。为什么ES会喜欢这样,以及如何解决?

Requset:

{ 'size': 1,'query': { 'bool': {'must': [ { 'match': {'_all': {'query': 'test','operator': 'and','fuzziness': '2'}}}],'should': [ { 'multi_match' : { 'query': 'test','type': 'best_fields','fields': ['ObjectData.PRTNAME','ObjectData.EXTERNALID','ObjectData.contactList.VALUE','*SERIES','*NUMBER','ObjectData.INN'],'operator': 'or','boost': 3 }}] } },'aggs': { 'byObjectID': { 'terms': {'field': 'ObjectID'},'aggs': {'latestVer': { 'top_hits': { 'sort': [{'creationDate': { 'order': 'desc' }}],'_source': { 'include': ['ObjectData.BRIEFNAME','creationDate','ObjectID' ]},'size': 1 }} } } }}

响应:

{ 'took': 16,'timed_out': false,'_shards': { 'total': 5,'successful': 5,'failed': 0 },'hits': { 'total': 87,'max_score': 5.3479624,'hits': [ { '_index': 'crmws','_type': 'participant','_id': 'AVFtAkIcSH3HWHh0wIkd','_score': 5.3479624,'_source': { 'mostRecentVersion': null,'UserLogin': 'ap','creationDate': '2015-12-04T12:40:43.292Z','_id': null,'ObjectID': 26784418,'EventID': null,'version_id': 3798,'ObjectTypeId': null,'ObjectData': {...},'ObjectTypeSysName': 'participant','versionNumber': null } }] },'aggregations': {'byObjectID': { 'doc_count_error_upper_bound': 0,'sum_other_doc_count': 0,'buckets': [ { 'key': 26745417,'doc_count': 21,'latestVer': {'hits': { 'total': 21,'max_score': null,'hits': [ { '_index': 'crmws','_id': 'AVFtQCCtSH3HWHh0wItF','_score': null,'_source': { 'creationDate': '2015-12-04T13:48:17.949Z','ObjectID': 26745417,'ObjectData': {'BRIEFNAME': 'Верный-Преверный В.
