Panduosou is an online search service focused on finding resources indexed on Baidu Netdisk. It brings together searchable information about publicly discoverable files, helping users locate material without browsing through the storage platform manually. The site describes itself as a professional netdisk resource search engine and highlights convenience as a central part of its offering.

Search results cover a broad mix of content, including novels, films, videos, and study materials. The website also features popular search terms and recently indexed queries, with examples spanning fiction titles, entertainment, television series, and other subjects. Listings may include an indication of when a resource was added to the index, such as within the past few days, weeks, or months.

Panduosou states that its results come from resources publicly indexable on Baidu Netdisk and that it provides an aggregated search for resource information. Its role is therefore to help users discover relevant links and listings, rather than to present itself as the source or host of the files themselves.
