Lyndapodcast, teaches you, via InDesign expert and graphic designer Michael Murphy, teaches you how to specify exact match and range in GREP using InDesign. Use CTRL + F and then choose the GREP tab. Go to the special characters menu to the right and under Wildcards choose Any Digit. After \d you can add \d again, but you should use \d for double digits. For two or more digits use \d[2,]. You can also use \d[3,] for three or more digits. The last operation is \d[2,4] which gives you a minimum of 2 digits and a maximum of 4. This will create more accurate expressions.
