如果 Vespa 查询超时，部分结果

Question

如果结果集中的一个文档是一个巨大的文档（几 MB），那么：

查询超时（看起来查询速度很快 - 但使用 summary: dynamic 创建片段超时）
children: [...]只包含垃圾信息

这些解决方案中的一种可行吗？

如果 Vespa 无法回答 field: [...]，它至少应该回答文档 ID，例如id: "id:post:post::12345" 而不是 id: "index/content/0/..."
只有大文档的片段应该超时（目前所有 children: [...] return "id": "index/content/..."）

Answer 1

一般：

预计为大型文档生成片段不会花费那么长的时间 - 有问题的文档有多大？超时前经过了多少时间？（您可以通过在查询中添加例如 &tracelevel=5 来查找计时详细信息。
snippets中绝对不会出现垃圾信息，能举个例子吗？您确定这不是客户端问题吗？

针对您的具体问题：

ID 是摘要的一部分，因此如果摘要请求失败，它无法立即为您提供完整的 ID。如果您愿意，您可以自己执行此操作，方法是将 id 放在不同的摘要 class 中并首先请求（来自搜索者对不同的摘要 class 进行两次 "fill" 调用）。
每个分区节点都有一个摘要请求（通常针对多个 ID）。当您接近超时时，可以 return 我们拥有的内容，但据我记得，我们今天不会对摘要请求执行此操作。

无论如何，在考虑解决方法之前，让我们先找出原因，我不记得以前任何应用程序都有这个问题。我建议你在 https://github.com/vespa-engine/vespa/issues 创建一个问题，因为它更适合这样做。
