say had text said "please see pp. 45, 50 , 90 more info."

 

searching pp.*[0-9]+ match "pp. 45, 50 , 90" because extends ".*" far can matching number @ end.

 

however, searching pp.*?[0-9]+ match "pp. 45" because stops @ shortest match.

 

is mean?

 

it makes huuuuge difference if trying grep replacement within html code, because if try , search next closing angle bracket , forget less greedy "?" symbol, match rest of document!
