# 故障排除

## 解决常见问题

以下建议可帮助你排查文档处理系统中的常见问题，包括字段无法正确捕获数据、OCR 错误以及验证规则问题：

### 字段无法正确捕获数据：

* 检查相关字段的配置，确认使用了正确的字段类型，并且所有必需属性都已正确设置。
* 确保用户获得了正确的说明，知道如何在字段中正确输入数据；如有需要，请提供培训或指南。
* 如果问题仍然存在，请运行测试，确认这是系统性问题，还是只会在某些输入情况下发生。这有助于你更准确地确定问题原因。

### OCR 错误：

* 检查扫描文档的质量，包括文本是否清晰易读，以及是否存在变形或模糊。
* 调整 OCR 设置，包括语言、文本识别算法和其他参数，以提高准确性。执行 OCR 预览或测试运行，检查 OCR 系统的性能并找出可能的错误来源。
* 如果 OCR 错误持续存在，可以考虑采用高级 OCR 系统，或了解外部 OCR 服务。

### 验证规则问题：

* 检查验证规则的配置，确保规则设置正确并符合预期标准。
* 确保验证规则没有过于严格，并且充分考虑了实际数据。
* 运行测试，确认验证规则按预期工作，并检查其对意外数据或边缘情况的响应是否恰当。
* 向用户提供指导和错误消息，提醒他们注意验证错误，并帮助他们输入正确的数据。

通过系统地检查和排查这些常见问题，你可以提升文档处理系统的性能和准确性，并确保系统平稳、高效地运行。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.docbits.com/chinese/guan-li-yu-she-zhi/settings/global-settings/document-types/fields/troubleshooting-2.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
