Hi!

 i have a  simple question,  if the master table have an index, must  i have create  the same index in a child  table?
what is  the best practice  for  indexes  in table partition ?

Indexes are self-contained within the physical table on which they are defined.  The index on the master contains no rows that are present in the child table.
