What does dragnet mean?
A dragnet is, literally, a large net that is dragged along the bottom of a body of water to catch fish — a technique used by commercial fishermen for centuries. In modern English, however, the word far more often appears in its figurative sense: an extensive, coordinated search conducted by police or other authorities to catch a suspect or round up a group of individuals. Journalists frequently write of a 'citywide dragnet' after a high-profile crime or escape, evoking the image of a net being pulled across an entire area so that no one can slip through. The word's connotations tend toward thoroughness and inevitability, but also toward indiscriminateness: a dragnet sweeps up everyone within its reach, including people who may have nothing to do with the matter at hand. This double edge makes it a vivid choice when describing both the efficiency and the collateral reach of large-scale searches.

Etymology of dragnet
Dragnet is a straightforward compound of the English words drag and net, formed from the verb drag (of Germanic origin, related to draw) plus the noun net (Old English 'nett', also Germanic). The compound arose naturally in English to describe nets pulled through water, with use attested by the early 18th century. Its figurative application to police searches developed later, drawing on the image of sweeping up everything in a netted area, and was popularized in 20th-century American usage partly through media such as the radio and television series Dragnet.
How dragnet is actually used
Primarily used as a noun. The literal fishing sense is now relatively rare compared to the figurative law-enforcement sense, which dominates modern usage, especially in journalism. Often carries a slightly ominous connotation of sweeping, indiscriminate capture — those caught up in a 'dragnet' may be innocent bystanders rather than intended targets.
