【问题描述】:
ES 版本:1.5 (Amazon Elasticsearch)
我的目标:在某个字段上获得带有重复数据删除的搜索结果。我目前正在对处理重复数据删除的聚合进行一些研究。所以,我的结果是一个包含 1 个大小的桶的列表桶。但是,我找不到对存储桶列表进行排序的方法。
当前查询:
curl -XGET "http://localhost:9200/myidx/product/_search?search_type=count" -d '{
"size": 2,
"query": {
"function_score": {
"field_value_factor": {
"field": "relevance",
"factor": 2.0
},
"query": { "term": { "title": "abcd" } },
"score_mode": "multiply",
"boost_mode": "multiply"
}
},
"aggs": {
"unique": {
"terms": {
"field": "groupid",
"size": 2
},
"aggs": {
"sample": {
"top_hits": {
"size": 1
}
}
}
}
}
}'
结果:
{ ...
"aggregations": {
"unique": {
"doc_count_error_upper_bound": 1,
"sum_other_doc_count": 39,
"buckets": [
{
"key": 717878424,
"doc_count": 14,
"sample": {
"hits": {
"total": 14,
"max_score": 45.856163,
"hits": [
{
"_index": "myidx",
"_type": "product",
"_id": "89531",
"_score": 45.856163,
"_source": { ... }
}
]
}
}
},
{
"key": 717878423,
"doc_count": 8,
"sample": {
"hits": {
"total": 8,
"max_score": 68.78424,
"hits": [
{
"_index": "myidx",
"_type": "product",
"_id": "89517",
"_score": 68.78424,
"_source": { ... }
}
]
}
}
}
]
}
}
}
我希望看到 max_score=68.78424 作为第一个存储桶的第二个存储桶。这可能吗?
如果聚合不是推荐的解决方案,请告知。
