Question

我正在尝试使用可搜索的博客条目模型，它在开发平台上运行良好但是当我尝试在云中添加条目时出现错误：

Traceback (most recent call last):
File "/base/python_runtime/python_lib/versions/1/google/appengine/ext/webapp/init.py", line 517, in call
    handler.post(*groups) File

    raise self.exception
ApplicationError:

ApplicationError: 1 Too many indexed > properties for entity: app:

it over the limit: entity_type: "Article",ancestor: false,
Property { name: "searchable_text_index", direction: ASCENDING},
Property { name: "searchable_text_index", direction: ASCENDING},
Property { name: "date", direction: ASCENDING}

这些条目不是那么大（<500字）是低限吗？我能想到解决这个问题的唯一方法是将条目存储为不可搜索的模型，并将条目文本分解为较小的可搜索模型，每个模型都引用主条目。非常感谢任何帮助

您似乎遇到的是爆炸指数。您可以在此处详细了解它们：http://code.google.com/appengine/docs/python/datastore/queries.html#Big_Entities_and_Exploding_Indexes

除非您拥有非常小的数据集，否则基本上您无法使用AppEngine创建全文引擎。要么你会遇到爆炸式索引，要么遇到其他问题（即合并加入超时）。我建议您查看名为IndexTank的服务，这是一个非常好的全文搜索服务。它有一个完整的REST api和python客户端，所以很容易上AppEngine。

克服appengine搜索的大小条目大小限制？
