[iBook] OFF TOPIC: web site question

[gooddog at interlync.com]

Is it possible for a web site to make their text unsearchable  
somehow? I ask because I stumbled across a web site with a friend's  
name and a quote from them, but when I searched on google using text  
from the quote and their name, nothing came up at all. I tried again  
using the subject of the website and the person's name, but nothing  
came up. Is there a way to look at the code to see what is going on?  
Is this a usual practice?

Thanks in advance.
