description: FastGPT SearXNG 搜索插件配置指南
|
|
---
|
|
|
|
[SearXNG](https://github.com/searxng/searxng)是一款免费的互联网元搜索引擎，它汇总了来自各种搜索服务和数据库的结果。它不会跟踪或分析用户。用户可以自行部署它进行使用。本文介绍 Searxng 的部署以及接入 FastGPT 插件。
|
|
|
|
|
|
## 1. 部署应用
|
|
|
|
这里介绍在 Sealos 中部署 SearXNG 的方法。Docker 部署，可以直接参考 [SearXNG 官方教程](https://github.com/searxng/searxng)。
|
|
|
|
点击打开 [Sealos 北京区](https://bja.sealos.run?uid=fnWRt09fZP)，点击应用部署，并新建一个应用：
|
|
|
|

|  |  |
|
|
|
|
## 2. 部署配置
|
|
|
|
把下面参数，填入配置中：
|
|
|
|
* 镜像名: searxng/searxng:latest
|
|
* CPU: 0.2
|
|
* 内存: 512M
|
|
* 容器暴露端口: 8080
|
|
* 开启公网访问
|
|
* 点击高级配置，填写环境变量和配置文件
|
|
|
|
|
|
|
|
**环境变量**
|
|
|
|
填下面两个内容，主要是为了减小并发，不然内存占用非常大。
|
|
|
|
```
|
|
UWSGI_WORKERS=4
|
|
UWSGI_THREADS=4
|
|
```
|
|
|
|
**配置文件**
|
|
|
|
新增一个配置文件，文件名：`/etc/searx/settings.yml`
|
|
文件内容：
|
|
|
|
```txt
|
|

|
|

|
|
|
|
default_doi_resolver: 'oadoi.org'
|
|
```
|
|
|
|
国内目前只有 Bing 引擎可以正常用，所以上面的配置只配置了 bing 引擎。如果在海外部署，可以使用[Sealos 新加坡可用区](https://cloud.sealos.io?uid=fnWRt09fZP)，并配置其他搜索引擎，可以参考[SearXNG 默认配置文件](https://github.com/searxng/searxng/blob/master/searx/settings.yml), 从里面复制一些 engine 配置。例如：
|
|
|
|
```
|
|
- name: duckduckgo
|
|
engine: duckduckgo
|
|
shortcut: ddg
|
|
|
|
- name: google
|
|
engine: google
|
|
shortcut: go
|
|
```
|
|
|
|
## 3. FastGPT 使用
|
|
|
|
复制 Sealos 部署后提供的公网地址，填入 FastGPT 的 SearXNG 插件的 URL 中。

|
## 返回格式
|
|
|
|
* 成功时返回搜索结果数组：
|
|
|
|
```bash
|
|
{
|
|
"result": "[{\"title\":\"标题1\",\"link\":\"链接1\",\"snippet\":\"摘要1\"}, ...]"
|
|
}
|
|
```
|
|
|
|
* 搜索结果为空时会返回友好提示：
|
|
|
|
```bash
|
|
{
|
|
"result": "[]",
|
|
"error": {
|
|
"message": "No search results",
|
|
"code": 500
|
|
}
|
|
}
|
|
```
|
|
|
|
* 失败时通过 Promise.reject 可能返回错误信息：
|
|
|
|
```bash
|
|
- "缺少查询参数"
|
|
- "缺少url"
|
|
- "Failed to fetch data from Search XNG"
|
|
```
|
|
|
|
一般问题来源于参数缺失与服务部署，如有更多问题可在用户群提问。
|
|
|
|
## FAQ
|
|
|
|
### 无搜索结果
|
|
|
|
1. 先直接打开外网地址，测试是否可以正常搜索。
|
|
2. 检查是否有超时的搜索引擎，通过 API 调用时不会返回结果。
