Question

我使用Django Web框架集成了Elasticsearch和haystack。现在我要删除不存在的使用 call_command（'update_index --remove'）函数从Elasticsearch索引中获取数据。

我的问题是当我运行 update_index --remove 时，出现以下错误：

我正在使用：
django-haystack == 2.8.1
elasticsearch == 7.1.0
elasticsearch-7.4.0 => 服务器

注意：
不推荐

HAYSTACK_SIGNAL_PROCESSOR ='haystack.signals.RealtimeSignalProcessor'

此方法不适合我。我没有使用django进行数据插入。仅用于过滤和删除目的。

update_index --age = 24 的相同问题。

我认为问题在于您正在使用Elasticsearch 7和Haystack only supports versions up to 5：

Haystack当前仅支持Elasticsearch 1.x和2.x。尚不支持Elasticsearch 5.x，如果您需要帮助，请参阅＃1383。

我看到两个选择：

保持干草堆并使用Elasticsearch 5服务器，
抛弃干草堆并使用“ vanilla” Elasticsearch python client，然后手动执行查询（也可以执行简单的HTTP请求）。

您看到的错误：

TypeError：search（）得到了意外的关键字参数'doc_type'

与在Elasticsearch 7中已删除文档类型这一事实有关。

希望有帮助！
