That's the art of Google-fu
The trick is to include the most distinctive words."control" rather than "turn" and "on"
That would work:

"raspberry" or "raspberry pi" to get specifics for Pi.
"gpio" is very specific to how the control would work so that's a good one to use.
Don't bother with words like "using" unless they are part of an exact phrase, then include the phrase in quotes.
In this case "LED" is not so significant. You want to light an LED, but info on controlling GPIO would be relevant whatever device was attached. It doesn't hurt, but on it's own it lacks the core query point.
Here's another search that may be useful.
