参数

search_condition: Must be a valid SQL expression used to match the documents to modify. This expression might be as simple as true, which matches all documents, or it might use functions and operators such as 'CAST(_id AS SIGNED) >= 10', 'age MOD 2 = 0 OR age MOD 3 = 0', or '_id IN ["2","5","7","10"]'.

返回值
