搜遍 (sōu biàn) is a compound verb meaning 'to search everywhere' or 'to search thoroughly throughout a place or area.' It combines 搜 (sōu), meaning 'to search' or 'to scour,' and 遍 (biàn), meaning 'all over,' 'everywhere,' or 'throughout.' Together, they emphasize exhaustive, methodical searching—not just a quick look, but covering every possible location or possibility.

This word is commonly used in contexts involving lost items, investigations, or urgent searches—such as looking for keys, missing pets, or evidence. It often appears with a direct object indicating the scope of the search (e.g., 搜遍整个房间 'searched the entire room') and may be followed by result-oriented phrases like 找到了 (found it) or 也没找到 (still couldn’t find it). While formal enough for written reports, it’s also frequent in everyday spoken Chinese when describing persistent, diligent searching.
