Well, Google doesn't show validation exceptions if you mistype the  
query ;) But you get the results you expected anyway. So your query is  
"fixed", it it contains a syntax error.

Yes, you are right, and I suppose writing a simple version which would  
escape any mistyped charaters shouldn't be very hard.
