Elasticsearch 7 [标准] token 过滤器已被删除

Question

我正在尝试升级到 Elasticsearch v7(我使用的是 ruby​​/rails 客户端)，在这样做并修复了一些东西后，我遇到了以下错误

Elasticsearch::Transport::Transport::Errors::BadRequest:
  [400] {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"The [standard] token filter has been removed."}],"type":"illegal_argument_exception","reason":"The [standard] token filter has been removed."},"status":400}

在检查破坏性变化时，确实提到

The standard token filter has been removed because it doesn’t change anything in the stream.

我不确定我应该如何在我的配置中反射(reflect)这一点。如果我理解正确，此错误可能来自我的自定义短语建议器

{
  "analysis": {
    "filter": {
      "shingle": {
        "type": "shingle",
        "min_shingle_size": 2,
        "max_shingle_size": 3
      }
    },
    "analyzer": {
      "trigram": {
        "type": "custom",
        "tokenizer": "standard",
        "filter": ["standard", "shingle"]
      },
      "reverse": {
        "type": "custom",
        "tokenizer": "standard",
        "filter": ["standard", "reverse"]
      }
    }
  }
}

我应该删除 tokenizer field ？也许他们忘了更新它，但这仍然是 [Elasticsearch documentation of the suggester][1] 中提到的内容。

如果问题不是从那里来的，我应该去哪里查看？

ES 7.3.2

elasticsearch-api-7.3.0 | Elasticsearch 传输 7.3.0

Elasticsearch 模型 7.0.0 | Elasticsearch 导轨 7.0.0
