We Live In A Crazy World
I'm sure plenty of people out there have experienced looking for information on a website, only to be forced to go to Google and search for it via the "site:" option.
Well, I have a book on the Eclipse Rich Client Platform. I consulted the index to find information about Retargetable Actions. Unfortunately I didn't find anything.
The result is a section of the book I already have.
So, in effect, because I couldn't find the information in the index, I wound up using Google to find the section of the book I was looking for.
