That's a correct behaviour: the ``*´´ in a regular expression stands  
for 0 to ∞ repetitions of the last character. So indeed you are  
searching for everything that contains at least ``cl´´.


If some characters play no role, then don't mention them – or do you  
like to talk a lot about something that does not matter anything to  
anyone? This expression might be more useful:

	cla.*

(I do not use the regexp form in TeXShop. It's not clear to me  
whether there is some correspondence from my input to the output,  
except when I am *not* using any wildcards. I prefer GNU Emacs, which  
would find with either of these expressions all occurrences of \index 
{*}:

	\\index{[^}]+}
	\\index{[^}]*?}

backslash index { with an unknown number of characters of which is  
*none* a } ending in })
