Meaning
どこか is used to indicate an unspecified or uncertain location. The particle か added to question words like どこ (where) makes them indefinite. Similar patterns include なにか (something) and だれか (someone). When used with the particle へ and a movement verb, どこか can be used in questions like どこかへ行きますか (Are you going somewhere?), though へ can be omitted.
