Look for Text Skipping the Comments

[Lorenzo Isella]

Dear All,
Suppose you are writing some code with a lot of documentation in the 
form of comments within the code itself. Now, if you use C-s to look for 
a word, emacs will also search though the comments.
Is there a way to tell emacs that it should look for a 
word/expression/string skipping the comments?
Many thanks

Lorenzo
