find search item plus 4 lines before and after

I am using notepad++ and would like to find the context in which a particular string occurs.

So the search string is 0wh.*0subj and I would like to find this search item plus 4 lines immediately before and after it.

eg: xxx means whatever is on a new line. the search result should be:
xxx
xxx
xxx
xxx
0wh.*0subj
xxx
xxx
xxx
xxx

I have tried using \n\r but its not working. Any assistance afforded would be greatly appreciated.

Regards

This will work in Notepad++ (tested):

(?m)(^[^\r\n]*\R+){4}0wh\.\*0subj[^\r\n]*\R+(^[^\r\n]*\R+){4}

On the screenshot, note that the 555 line is not selected. It is just the current line.

                         # matching start and end of line) (case-
                         # sensitive) (with . not matching \n)
