多个索引的弹性搜索多个大小选项

Question

我的目标：为 index1 返回 15 个结果，为其他索引返回 10 个结果

我的问题：由于“hotel_name”是最重要的字段，并且它只存在于第一个索引中，因此根据查询，响应只有来自 index1 的数据

请求 URL: "/index1,index2,index3/_search?size=25"

{
  "query": {
    "multi_match": {
      "query": "hotel",
      "type": "phrase_prefix",
      "fields": [
        "hotel_name^9",
        "country^8",
        "city^7",
        "destination^6",
        "state^5",
        "zone^4",
        "title^3",
        "description_short^2",
        "description^1"
      ]
    }
  }
}

您不能在多索引 _search 查询上设置多个大小，但您可以使用 Multi Search API 并为每个索引查询设置不同的大小。

GET _msearch
{"index": "index1"}
{
  "size": 15
  "query": {
    "multi_match": {
      "query": "hotel",
      "type": "phrase_prefix",
      "fields": [
        "hotel_name^9",
        "country^8",
        "city^7",
        "destination^6",
        "state^5",
        "zone^4",
        "title^3",
        "description_short^2",
        "description^1"
      ]
    }
  }
}
{"index": "index2"}
{
  "size": 10
  "query": {
    "multi_match": {
      "query": "hotel",
      "type": "phrase_prefix",
      "fields": [
        "country^8",
        "city^7",
        "destination^6",
        "state^5",
        "zone^4",
        "title^3",
        "description_short^2",
        "description^1"
      ]
    }
  }
}
{"index": "index3"}
{
  "size": 10
  "query": {
    "multi_match": {
      "query": "hotel",
      "type": "phrase_prefix",
      "fields": [
        "country^8",
        "city^7",
        "destination^6",
        "state^5",
        "zone^4",
        "title^3",
        "description_short^2",
        "description^1"
      ]
    }
  }
}

您可以使用Query Templates 来避免重复。
