I assume you mean you want to earliest, not the latest, but if you really mean latest, flip the sign here.

UPDATE SearchTrack ;
   SET Search_Name = m.NewName, ;
           Search_Desc = m.NewDesc, ;
           Search_Date= DATETIME() ;
   WHERE Search_Date = (SELECT MIN(search_date) FROM SearchTrack)

I've assumed that Search_Date is actually a DateTime, so that it can be used to actually uniquely choose the oldest. If it's just a date, you have to deal with the possibility of having two records with the same value. (Technically, that's true for datetime as well, but that seems unlikely in your use case.)
