I am searching for a word, in this case "hehe" that is located in the file findTest

by using grep, but when i initiate the search:

grep -r "hehe"

or

grep -lr "hehe"

it starts but after 5 min waiting nothing happens, even if i am in the same directory as the file.
the only way i get a results straight away is being in the same directory and typing:

grep "hehe" findTest 

Are their any other ways to search for a word? even if not in the same directory.
