Can someone tell me where I can find the search functions on the site referenced below?

    2.  When searching on "provider's phone number:", enter just the last seven digits, and leave both the area code and city fields blank.  If any profiles exist in the database with the phone number, this approach will find it -- regardless of any data entry errors in the city or area code fields submitted by previous reviewers.

 
    3.  When searching on "provider's name:", first try searching on just the name, and leave both the city and area code fields blank.  If this returns a large number of responses, then start adding in additional filters, one at a time.  First add "city:", and see if the desired profile appears.  If not, remove the "city:" value and use "area code:".
