更新架构错误 Api - Google 云搜索

Question

我目前正在使用 Google 云搜索 REST Api，当我尝试更新我的架构时出现以下错误。有人可以解释为什么吗？

 {
  "error": {
    "code": 400,
    "message": "Disallowed schema change for previously deleted property: Cannot change is_repeated from true to false. Disallowed schema change for previously deleted property: Cannot change the retrieval importance of a text property.",

正如此处文档中所说：https://developers.google.com/cloud-search/docs/guides/schema-guide、

"In situations where you must make an otherwise disallowed change to your schema, you can often make a series of allowed changes that achieve the same effect. In general, this involves first migrating indexed properties from an older object definition to a newer one and then sending an indexing request that uses only the newer property."
