What is yuexin-search?

Yuexin Search is a self-hosted web application for organizing and searching resources stored across multiple Chinese cloud storage services. It supports Quark, Baidu, Aliyun, UC, and Xunlei cloud drives, letting a site operator index links from those services and expose them through a single search interface. The project does not store any files or resource links itself, everything has to be configured by whoever deploys it. This version 4.0 is a fork and extension of the earlier xinyue-search project. The main additions are a multi-layer caching system that stores search results, directory trees, and runtime data separately to speed up repeated queries. A validity-checking step can filter out expired cloud links before they appear in search results, and can connect to a third-party checking service for deeper verification. The front end includes a theme system. The default and a custom theme called mofa are both included, with the mofa theme getting notable attention in recent updates: mobile improvements for immersive scrolling backgrounds, a dark mode, bottom navigation tabs, and an iOS-style announcement popup. The admin panel handles all configuration, including which resource APIs to connect to, what themes to display, and how caching behaves. There is a built-in installer that sets up the database on first run. The README is written in Chinese and is directed at a Chinese-speaking audience. It is explicit that the project is for technical learning and personal use only, and that the author takes no responsibility for any illegal use. No resource content is bundled or provided, and users are responsible for supplying their own API endpoints and cloud drive configurations. A full setup guide is linked to an external documentation site. The code is built on a PHP backend (references to ThinkPHP cache conventions appear in the changelog) with a JavaScript front end. It is released under the MIT license.
