elasticsearch - 构面的 “facet_filter”字段等效什么，但要聚合？

Question

使用 facets 来考虑这个好要求:

{
   "facets": {
      "tag": {
         "terms": {
            "field": "text"
         },
         "facet_filter": {
            "term": {
               "lang": "en"
            }
         }
      }
   }
}

如何使用facet_filter功能切换到 aggregations而不是 facets？

{
   "aggs": {
      "tag": {
         "terms": {
            "field": "text"
         },
         "facet_filter": {       <--- Not working
            "term": {            
               "lang": "en"
            }
         }
      }
   }
}

Answer 1

您可以使用filter

{
   "aggs": {
      "tag": {
          "filter" : { "term" : { "lang" : "en" } },
          "aggs" : {
            "tag": {
              "terms" : { "field" : "text" }
            }
         }
      }
   }
}
