1. Overview

dsh-web-search-multi connects DeepSeek Harness to multiple search engines with automated fault tolerance:

• Free Zero-Key Direct Engines: 360 Search (real-time news and trending events), Bing, and Baidu direct search without any API keys.
• AI-Native Free Tiers: Tavily (1,000/mo), Brave Search (2,000/mo), Serper/Google (2,500 free), Bocha AI.
• Private & Self-Hosted: SearXNG with token authentication.
• Global Fallback: DuckDuckGo.
• Web GUI Control: Full graphical settings tab inside DSH Web UI (Settings -> 多源 Web 搜索) with live connection testing and instant persistence.
• Secure Credential Storage: Secrets saved securely to ~/.dsh/.credentials.yaml (mode 0600), non-secret settings saved to ~/.dsh/settings.yaml.

2. Compatibility

• Node.js: >= 20.0.0
• DeepSeek Harness: Verified on mainline v0.1.0+
• Platform: Linux / macOS / Windows

3. Install

As a standard DSH Profile Bundle, installation is one simple command:

dsh plugin --profile web add github:cinob/dsh-web-search-multi

Uninstallation

dsh plugin --profile web remove dsh-web-search-multi
