寻找 (xún zhǎo) is the general, everyday verb for 'to look for, to seek' — it works for both concrete objects (a lost wallet) and abstract things (truth, answers). It's more neutral and common than 寻求 (xún qiú), which is more formal and typically used for abstract goals or help. Other siblings like 搜寻 (sōu xún) imply a thorough search, and 寻觅 (xún mì) is literary.
