What does searchlight mean?
A searchlight is a powerful directional light used to scan an area or locate people and objects, often in darkness or at long range. Its beam can move across a landscape, harbor, road, or building as an operator searches for a target. The word also has an important figurative meaning: to put something “under the searchlight” is to examine it with intense public attention, scrutiny, or investigative interest. This metaphorical use is especially common in reporting about politics, businesses, celebrities, and public institutions. In its literal sense, a searchlight differs from an ordinary flashlight because it is generally more powerful, fixed or mounted, and intended to illuminate a distant or broad area. The term is understood in British and American English, though the figurative expression is particularly characteristic of formal journalism and public discussion.

Where does searchlight come from?
“Searchlight” is a compound formed from “search” and “light.” Its literal sense developed in the nineteenth century with the increasing use of powerful beam lights for military, maritime, and other nighttime searching. The figurative sense of public examination developed later by analogy with the way a searchlight reveals whatever it illuminates.
