# 重复项过滤器

重复筛选器可减少重复的业务记录。

## 保护层

* 当前搜索中的重复项
* 类别之间的重复项
* 在之前保存的搜索中发现的重复项

## 为什么最终结果可能会更少

当本地去重索引中已经存在大量候选项时，Geo Prospector 可能会低于目标完成，而不是返回重复记录。

## 操作建议

* 对于重复进行的活动，请保持筛选器开启。
* 备份本地数据文件夹。
* 应用程序运行时，请勿删除去重数据。
* 仅当您确实需要进行全新的市场扫描时，才使用干净项目策略。

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://visi-digital-internasional.gitbook.io/geo-prospector/geo-prospector-zh/kan-tan-gong-zuo-liu/duplicate-filter.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
