Return Adjacent Cell after Index-Match function

Question

I am trying to search a column in excel based on a string value and return the contents of the cell below it. The formula I currently have is returning the contents of the indexed cell, but I would like it to return the contents of the cell below instead.
A summary of the code as is:
=INDEX('Sheet4'!A:A,MATCH("*"&A2&"*",'Sheet4'!A:A,0),1,1)

Answer 1

For anyone who may need the answer, I've figured it out. I replaced the "1,1)" with "+1)"
