In the 1960s the Supreme Court strengthened protections against "unreasonable" searches and seizures by applying exclusionary rules, barring the use of illegally collected evidence in court. Since the 1980s, however, a more conservative Court has undercut the force of exclusionary rules, allowing the use of evidence collected "in good faith" even if without a valid warrant. Government officials have been given wider access to telephone and bank records, and a nationwide antidrug campaign has led to the use of "stop and frisk" searches, particularly in the nation's cities. In the 1990s congressional conservatives sought to write into federal statute the greater leeway allowed police by the Court.
2 In international law the right of search denotes the right of a warship to detain and search a private vessel belonging to a foreign national. In peacetime, this right is ordinarily exercised only within the territorial waters (see waters, territorial) of a state and merely as an incident of the power to police such waters, and generally only in such cases as suspected piracy, violation of fishing regulations, or interference with telephone cables. In wartime, however, a belligerent may search neutral vessels on the high seas in order to capture the property of enemy nationals or to remove contraband bound for enemy ports. Forcible resistance to search allows the warship to attack or destroy the vessel or its cargo or to take them as a prize. The right of search is also called the right of visit and search.
Tool for finding information, especially on the Internet or World Wide Web. Search engines are essentially massive databases that cover wide swaths of the Internet. Most consist of three parts: at least one program, called a spider, crawler, or bot, which “crawls” through the Internet gathering information; a database, which stores the gathered information; and a search tool, with which users search through the database by typing in keywords describing the information desired (usually at a Web site dedicated to the search engine). Increasingly, metasearch engines, which search a subset (usually 10 or so) of the huge number of search engines and then compile and index the results, are being used.

In law enforcement, an exploratory investigation of a premises or a person and the taking into custody of property or an individual in the interest of gaining evidence of unlawful activity or guilt. The latitude allowed police in carrying out searches and seizures varies greatly from country to country. In the U.S., the 4th Amendment to the Constitution prohibits unreasonable searches and seizures and requires that a warrant be issued following a finding of probable cause. The warrant must specify the place to be searched and the persons and things to be seized.
