我试图从ElasticSearch获取所有独特的suite_name字段，但我的aggs没有返回任何存储桶。Aggregation returns no buckets
我使用这个映射
{
"functional_tests": {
"mappings": {
"web_test_result": {
"properties": {
"duration": {
"type": "long"
},
"fail_category": {
"type": "string"
},
"fail_info": {
"properties": {
"message": {
"type": "string"
},
"screenshot_url": {
"type": "string"
},
"stack": {
"type": "string"
}
}
},
"fail_message": {
"type": "string"
},
"fail_stack": {
"type": "string"
},
"file": {
"type": "string"
},
"finish_time": {
"type": "date",
"format": "strict_date_optional_time||epoch_millis"
},
"instance_id": {
"type": "long"
},
"order_number": {
"type": "long"
},
"query": {
"properties": {
"term": {
"properties": {
"instance_id": {
"type": "long"
},
"suite_name": {
"type": "string"
}
}
}
}
},
"screenshot_url": {
"type": "string"
},
"size": {
"type": "long"
},
"status": {
"type": "string"
},
"suite_id": {
"type": "string"
},
"suite_title": {
"type": "string",
"fields": {
"raw": {
"type": "string",
"index": "not_analyzed"
}
}
},
"test_id": {
"type": "string"
},
"test_title": {
"type": "string",
"fields": {
"raw": {
"type": "string",
"index": "not_analyzed"
}
}
},
"timedOut": {
"type": "boolean"
}
}
}
}
}
}
这aggs
GET functional_tests/web_test_result/_search
{
"size": 0,
"aggs" : {
"suite_titles" : {
"terms" : {
"field" : "suite_title.raw",
"size" : 1000
}
}
}
}
返回我这个
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 3383,
"max_score": 0,
"hits": []
},
"aggregations": {
"suite_titles": {
"doc_count_error_upper_bound": 0,
"sum_other_doc_count": 0,
"buckets": []
}
}
}
如果我做aggs上suite_id，这是一个单一令牌，我得到桶。
