Surface Forms
Morphology
The expression joins the antonyms 'high' and 'low' with 'and' to indicate the full range of places (searching both high and low), so the sense 'everywhere' is a direct, predictable extension of the constituents. This opposites‑joined-to-mean-'everywhere' pattern is cross‑linguistically common, so a B1 learner who knows the words would very likely infer the MWE meaning.
Etymology
High and low gives a simple picture: people looking in the high places (like roofs and trees) and the low places (like under beds and in holes). So, saying you looked high and low means you searched 'everywhere'.
