我为 elasticsearch 中的“asset_test”索引配置了以下设置:

{
  "settings" : {
    "analysis" : {
      "analyzer" : {
        "str_filtered_search_analyzer" : {
          "tokenizer" : "keyword",
          "filter" : ["lowercase"]
        },
        "str_prefix_analyzer" : {
          "tokenizer" : "keyword",
          "filter" : ["lowercase", "prefix"]
        },
        "str_substring_analyzer" : {
          "tokenizer" : "keyword",
          "filter" : ["lowercase", "substring"]
        },
        "path_analyzer" : {
          "type" : "custom",
          "tokenizer" : "path_hierarchy"
        }
      },
      "filter" : {
        "prefix" : {
          "type" : "edgeNGram",
          "min_gram" : 2,
          "max_gram" : 24,
          "side": "front"
        },
        "substring" : {
          "type" : "nGram",
          "min_gram" : 2,
          "max_gram" : 24
        }
      }
    }
  },
  "mappings" : {
    "asset" : {
      "properties" : {
        "_id": {
          "type" : "string",
          "index" : "not_analyzed"
        },
        "_rev": {
          "type" : "string",
          "index" : "not_analyzed"
        },
        "type": {
          "type" : "string",
          "index" : "not_analyzed"
        },
        "requiredBySystem": {
          "type" : "boolean"
        },
        "attributes": {
          "properties" : {
            "id" : {
              "type" : "string"
            },
            "type" : {
              "type" : "string",
              "index" : "not_analyzed"
            },
            "heading" : {
              "type" : "string"
            },
            "text" : {
              "type" : "string"
            },
            "users" : {
              "type" : "string"
            },
            "categories" : {
              "type" : "multi_field",
              "fields" : {
                "categories" : {
                  "type" : "string",
                  "index" : "not_analyzed"
                },
                "path" : {
                  "type" : "string",
                  "analyzer" : "path_analyzer"
                }
              }
            },
            "choices" : {
              "properties" : {
                "text" : {
                  "type" : "string"
                },
                "checked" : {
                  "type" : "boolean"
                }
              }
            },
            "requiredBySystem": {
              "type" : "boolean"
            },
            "required": {
              "type" : "boolean"
            }
          }
        }
      }
    }
  }
};

我在索引中有这个文件:

       {

       },
       {
           "id": "9399fb27448b1e5dfdca0181620k81gt",
           "type": "select",
           "heading": "Select Menu",
           "choices": [
               {
                   "text": "Option 1",
                   "checked": false
               },
               {
                   "text": "Option 2",
                   "checked": true
               }
           ],
           "requiredBySystem": true
       }
   ]
}

我正在尝试使用以下查询查找文档,但未找到:

{
    "query": {
        "field": {
            "attributes.categories.path": "/Airport"
        }
    }
}

有点坚持如何使这项工作。

*更新:我将“属性”设为嵌套类型,现在使用以下查询进行查询似乎可以工作:

{
  "query" : {
      "nested" : { 
        "path" : "attributes",
        "query" : {
          "term" : {
            "attributes.categories.path" : "/Airport/Hangar 1"  
          } 
        }
      }
  }
}

我会以正确的方式解决这个问题吗?
