Manual page indexes not correlating to correct pages

And even exceeding the length of the manual in some cases

The index page is for old versions of the manual(and the one who updated the rest of the manual forgot about the indices!)

Indeed, that looks wrong. It's a little scary that the manual seems to have gotten smaller rather than bigger! I wonder how that happened. The version of the manual sitting on my desktop is correctly indexed. :~(

This is weird. Maybe you should use links instead of page numbers?
EDIT: You can use Control+F to search for keywords.

it should just be automated from whatever they're using to create the manual (sections and their locations should be put in the text itself)
taking the time to change all the numbers manually every time there's an edit would waste hours no matter how it's done
