我从 flex 搜索开始,并且一直试图进行一些聚合。基本上,我有一个数据集,包含以下形式的数据:
{
"name": "The Chef Restaurant",
"city": "New York",
"state": "New York",
"rating": "GOOD",
"type": "Continental"
}
现在,我想进行一些汇总,并在一个查询中获得所有的Continental餐馆,Good餐馆,New York餐馆。
请注意,我不希望统计所有类型的餐厅,而只希望统计特定类型的餐厅。而且,这些聚合是相互独立的。就是说,当我说“好”时,我并不一定希望它是“大陆”,它可以是意大利语或其他任何东西。
这是我尝试过的:
{
"size": 0,
"query": {
"match_all": {}
},
"aggregations": {
"good_restaurants": {
"filters": {
"match": {
"rating": "CONTINENTAL"
}
}
},
"continental_restaurants": {
"filters": {
"match": {
"type": "CONTINENTAL"
}
}
},
"restaurants_in_new_york": {
"filters": {
"match": {
"type": "CONTINENTAL"
}
}
}
}
}
这给了我错误:
{
"error": {
"root_cause": [
{
"type": "search_parse_exception",
"reason": "Unknown key for a START_OBJECT in [good_restaurants]: [match].",
"line": 9,
"col": 17
}
],
"type": "search_phase_execution_exception",
"reason": "all shards failed",
"phase": "query",
"grouped": true,
"failed_shards": [
{
"shard": 0,
"index": "test_master",
"node": "-aWy78_mRaaBMcOAeiN9tg",
"reason": {
"type": "search_parse_exception",
"reason": "Unknown key for a START_OBJECT in [good_restaurants]: [match].",
"line": 9,
"col": 17
}
}
]
},
"status": 400
}
我知道这似乎是一个简单的问题,但是我已经坚持了很长时间。任何帮助将不胜感激。
最佳答案
您可以按照以下方式使其按预期方式工作:
{
"size": 0,
"query": {
"match_all": {}
},
"aggregations": {
"selected_types": {
"filters": {
"filters": {
"good_restaurants": {
"match": {
"rating": "CONTINENTAL"
}
},
"continental_restaurants": {
"match": {
"type": "CONTINENTAL"
}
},
"restaurants_in_new_york": {
"match": {
"type": "CONTINENTAL"
}
}
}
}
}
}
}
