Elasticsearch查询不返回当前数据的记录

Question

我们有大约100万条记录的小型弹性搜索指数。 elasticsearch中的记录如下所示。

{
  _index: gobzersearchindex
  _type: searchField
  _id: V-BzuHMgSui1l-vxlqTeTg
  _score: 3.614574
  _source: {
    gobzId: 198992
    productAttributes: [
      {
        name: untag_words
        value: yebhi59413 puma bikini
      }
      {
        name: brand
        value: Puma
      }
    ]
    imageOptimized: 0
    multiColor: 0
  }
}

当我尝试查询索引时，我发现了一些不寻常的行为。我正在尝试以下查询。

{
  "bool" : {
    "must" : {
      "match" : {
        "productAttributes.value" : {
          "query" : "adidas",
          "type" : "boolean"
        }
      }
    }
  }
}

当我搜索查询字符串adidas时，我没有得到上述查询的结果，但是当我使用puma，benetton和其他品牌等查询字符串时，相同的查询会返回结果。我无法弄清楚我做错了什么。

编辑： 以下映射用于创建索引
