Thanks Zhiqiang.
Sure. If use CSE for Adsence, it is necessary to attach "partner-pub-" before userID:engineID.
Example: partner-pub-[userID]:[EngineID]
Since {UserID:EngineID} parameter is passed to Google as it is, those who are using CSE for Adsence need to input by format of "partner-pub-[userID]:[EngineID]".
