For bash: 'i' gives me "no indices found" and 'I' says "no index". I can do a '/' search, which finds some "-p" strings, but "n" doesn't work to find the next.
From some other comments, it sounds like "info" uses emacs at its core? So I suppose I'd have to learn some emacs commands, if that's the case.
info works without emacs, but some people prefer emacs' info viewer to the console one. The console viewer does have some idiosyncratic keybindings - for example, "n" means "next node at same level", and "}" means "search for next occurrence". "H" will give you a quick overview.
I'm surprised indexes aren't working for you - unfortunately I don't know of any suggestions to fix that.
