using info to search for an 'item'

so I have this handy little function: zhelp() { man zshall | less -p "^ $1" } ... but it's time I moved to 'info' and I trust there's a simple option to search for some ... not just a string ... but a ... sorry, I don't know the jargon ... but an 'entry' or 'heading' or 'item'. As above, in 'man' these always have seven spaces after the beginning of a line then the name of the 'item'. I looked at 'info info' but you hafta already know the jargon to make any sense of it. I'll bet this is easy if you already know the answer.
