high and low

All possible places

High and low means everywhere, in all possible places.

The phrase appears almost exclusively with verbs of searching: I've looked high and low for my keys.

The image is of searching both elevated and ground-level spaces—leaving no place unchecked.

Sometimes written as high and low.
