Search engines are classified into the following three categories based on how it works.
Crawler-based search engines: All crawler-based search engines use a crawler or bot or spider for crawling and indexing new content to the search database. There are four basic steps, every crawler-based search engines follow before displaying any sites in the search results. Crawling, Indexing, Calculating Relevancy and Retrieving the Result. Example are Google, Bing, and Yahoo!
Human-powered directories: Human-powered directories also referred to as open directory system depends on human-based activities for listings. Yahoo! Directory and DMOZ were perfect examples of human-powered directories.
Hybrid search engines: Hybrid Search Engines use both crawler-based and manual indexing for listing the sites in search results. Most of the crawler-based search engines like Google basically uses crawlers as a primary mechanism and human-powered directories as a secondary mechanism. For example, Google may take the description of a webpage from human-powered directories and show in the search results. As human-powered directories are disappearing, hybrid types are becoming more and more crawler-based search engines.
