我对Elasticsearch还是很陌生，想使用术语聚合来完成以下工作：
这是我的映射：
{
"mapping": {
"product": {
"properties": {
"category": {
"type": "keyword"
},
"features": {
"properties": {
"breedte": {
"properties": {
"id": {
"type": "long"
},
"measure": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"value": {
"type": "float"
}
}
},
"diepte": {
"properties": {
"id": {
"type": "long"
},
"measure": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"value": {
"type": "float"
}
}
},
"hoogte": {
"properties": {
"id": {
"type": "long"
},
"measure": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"value": {
"type": "float"
}
}
}
}
},
"name": {
"type": "keyword"
},
"url": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
}
}
}
这是我目前拥有的（用2个值选择“ breedte”，用1个选择“ hoogte”）
GET _search
{

"name":"desc"
},

}
}
],
"should":[
{
"term":{
"features.breedte.value":"750"
}
},
{
"term":{
"features.breedte.value":"590"
}
}
]
}
}
}
},
"aggs":{
"categories":{
"filter":{
"bool":{
"should":[

}
},
"aggs":{

我认为我走在正确的轨道上，结果似乎还不错，但是每个规范的值都是OR而不是AND，如果选择一个值，则规范的其他值将显示为0。我想要的是将值添加到选择中时得到的计数。我希望有人能指出我正确的方向。
答案 0 :(得分：0)
我想我离现在有点近了。我将所选规格与每个存储桶一起发送。我现在剩下以下两个问题：
post_filter修复此问题！ 这就是我现在所拥有的。有关如何进行的任何想法？
