Existing in a variety of types, all search engines procure information but organize it in a variety of unique ways, which is why there are so many different search engines. At a basic level, a search engine is one of two things: a Robot or a Directory. Though some search engines combine features of both, most are predominantly either Robots or Directories.
A Robot uses a software program to search, catalog, and then organize information on the Internet. Organization of data can be completed in a number of ways—including through a harvester, robot, spider, wanderer, and worm—and employing diverse ways of searching Websites to gather data.

Software that looks for data that match the criteria in a query. Although search engines have been around for decades, they were brought to the forefront after the Web exploded onto the scene. Search engines differ in the way they find and index the content on the Web and the way they search those indexes to locate matches.
