user search

Hi ,
I'm new here , good to see the forum helping so much. Keep up the good work.

My question is :: previously i had created a drupal site in 5.X and in the user module i had an option to search for existing users based on email , name etc. Now i have created another drupal site in 6.X and some how i dont see that option anymore in this version. Can anyone help me with this problem. Do i have to install a module or something??
