如果Vespa查询超时，则部分结果。

Question

如果结果集中的一个文档是一个巨大的文档(几个MBs)，那么：

查询超时(似乎查询速度很快，但是使用out)

• children: [...]创建代码段只包含垃圾信息

)。

这些解决方案之一是可行的吗？

如果Vespa不能回答id: "index/content/0/..."

• Only，它至少应该回答文档id，例如，将"id": "index/content/...")

替换为field: [...]，大型文档的片段应该超时(目前children: [...]返回的都是field: [...])。

Answer 1

常规：

1. --为大型文档生成代码段不需要那么长的时间--问题文档有多大？超时前已经过去了多少时间了？(您可以通过将&tracelevel=5添加到查询中来查找时间细节。
2. -绝对不希望代码片段包含垃圾信息，您能给出一个看到的例子吗？你确定这不是客户端的问题吗？

关于你们的具体问题：

• -- id是摘要的一部分，因此如果摘要请求失败，它就不能立即给出完整的id。如果您愿意，您可以自己这样做，方法是将id放在不同的摘要类中，并首先请求(从搜索器对不同的摘要classes).
• There执行两个“填充”调用)是对每个分区节点的一个摘要请求(通常为多个id)。当您接近超时时，可以返回我们所拥有的内容，但据我所知，今天的摘要请求不会这样做。

无论如何，在考虑解决办法之前--让我们找出原因--我不记得以前任何应用程序都遇到过问题。我建议您在https://github.com/vespa-engine/vespa/issues创建一个问题，因为它更适合这样做。
