When performing searches in friendster, some searches allow you to select the depth of the profiles to search. A value of '1' is your direct friends, '2' is friends of friends, etc. In some places, you can no longer select the profile depth, and in other places the profile depth is limited to 2. If there is a limit in place, or there is no filter available, perform a normal search and you can then update the URL of the search results to add a profile depth value to your liking. Once you have the search results, look in the URL in your address bar. If there is already a parameter in there called profiledepth, you can update the value by just editing the URL and hitting Enter. I've found that even when the interface limits the depth to 2, it will accept values of up to 4 in the address bar.

If there is no profile depth option on the select page, go to the address bar and add this to the end of the URL and hit Enter: &profiledepth=2. This will select a profile depth of 2, change the number to get the value you want.
