DeepSeek Harness (DSH) WebUI Custom Search Plugin: dsh-cust-search

dsh-cust-search is a highly available web search plugin within the DeepSeek Harness ecosystem. It allows users to configure multiple search engines in the DSH WebUI and execute searches sequentially. If the current engine fails or times out, the plugin automatically switches to the next enabled engine until a valid result is obtained. The plugin natively supports 11 search engines, covering both public and paid AI services. Users can install it with a simple command-line command and enable it by checking it in the WebUI. By replacing single-engine search with multi-engine coordination, the tool significantly improves the stability of agents retrieving real-time information, making it suitable for developers with high requirements for search reliability.
