如何根据字段值过滤 ElasticSearch 结果？

Question

下面是我的示例搜索响应，检索到 4 个结果。

                "fields": {
                    "lastModified": [
                        1461738451720
                    ],
                    "dir": [
                        "/private/dholaria"
                    ],
                    "filename": [
                        "Report_google_Private"
                    ]
                },
                "highlight": {
                    "filename": [
                        "Report_google_Private"
                    ]
                }
            }
        ]
    }
}

现在，我想根据以下条件根据特定 "dir" 字段值过滤上述搜索结果。

当且仅当：

在响应中包含搜索结果

• 如果 "dir" 字段值等于：“/shared”或“/private/hitesh”
• 否则，如果 "dir" 字段值以以下任一开头：“/shared/”或 "/private/hitesh/"

如何在ElasticSearch中实现上述功能？

PS: 下面是我的示例映射。

试试这个查询：

{
  "query": {
    "bool": {
      "should": [
        {
          "term": {
            "dir.raw": {
              "value": "/shared"
            }
          }
        },
        {
          "term": {
            "dir.raw": {
              "value": "/private/hitesh"
            }
          }
        },
        {
          "match_phrase_prefix": {
            "dir.raw": "/shared"
          }
        },
        {
          "match_phrase_prefix": {
            "dir.raw": "/private/hitesh"
          }
        }
      ]
    }
  }
}
