核心畫面
One picture can hold this word: a movement that is quick, light and over in a second. A lamb skips, jumps and turns in the grass. A guard's hands sweep fast down a jacket and are gone. Both are short bursts of movement with nothing heavy about them. This is offered as a way to hold the word together, not as a claim that one meaning grew out of the other.

frisk 可以想成一個又快又輕、一下子就結束的動作。一邊是小羊在草地上蹦一下、轉個身、再蹦一下。另一邊是保全的手在你外套上迅速掃過，幾秒鐘就放行。兩個畫面的共同點是短、是快、是不拖泥帶水。這只是幫助記憶的想法，不是說搜身的意思一定由蹦跳的意思演變而來。From the word’s history
The source in this packet traces frisk to Middle English frisk (lively, frisky), from Middle French frisque (lively, jolly, blithe), of Germanic origin and ultimately a doublet of fresh. So the oldest recorded feel of the word is liveliness. The packet does not explain how the searching use arose, and this map does not claim to.
這份資料的來源說，frisk 來自中古英語 frisk（活潑的），再往前是中古法語 frisque（活潑、輕快），源頭是日耳曼語，和 fresh 同源。所以這個字有紀錄的最早感覺就是有活力、輕快。至於搜身的用法是怎麼出現的，來源沒有說明，這裡也不做推論。

快速掃過身體的搜查
同樣是短促快速的動作，只是動的不再是動物的四條腿，而是別人的一雙手。這是教學上的聯想，不是歷史演變的主張。
