Mi文档搜索 is a Chinese resource-search platform focused on finding documents and other files shared through major cloud-drive services. It aggregates publicly available listings and sharing links from platforms including Baidu Netdisk, Alibaba Cloud Drive, Quark, 115, and Xunlei, helping users search across services from one place. The site presents itself as a specialist search engine for document-related resources and also highlights broader materials, with popular searches spanning exam papers, Python tutorials, postgraduate mathematics, software, novels, presentation templates, and early-learning resources.

A frequently updated trending list showcases currently popular file names and collections. Mi文档搜索 states that its listings are collected automatically from public internet information and that it does not store, create, or distribute the files or cloud-drive content themselves. Users are directed to third-party services to access results and are responsible for complying with applicable laws when downloading or sharing.

The site also provides an email contact for rights holders to report potentially infringing listings, which it says it will review for removal or keyword blocking
