# What should go into index of the document? [closed]

So I have written a programming book and now I am adding \index for different keywords and terms. I am wondering what should I really put into index? If I mention keyword in the document 10 times, should I \index{keyword} every one of them or just the first? What makes the index good and what doesn't?

While this is an interesting question, I'm not sure that it is on-topic. –  Caramdir Jun 2 '11 at 20:18
I second Caramdir's opinion. A good index must be left to a professional indexer: "Writing an index does not come naturally, like breathing. It is more like playing the fiddle: some learn to do it reasonably well, a few will become virtuosi, but most people will never know how to do it. This simple truth seems lost on publishers and editors. Hans H. Wellisch –  Gonzalo Medina Jun 2 '11 at 20:33
