Meaning and types of search engine with Examples of search engines.

A search engine is a type of software that helps you find information on the internet. There are many different types of search engines, but the most popular ones are Google, Yahoo, and Bing. Each search engine has its own algorithms (or rules) for how it ranks websites.

The word “search engine” can also refer to the entire website that provides the search functionality. For example, when you type a query into Google, the results page that appears is the Google search engine.

Most search engines allow you to specify what kind of information you’re looking for. For example, if you want to find images of cats, you can use a search engine to search for “cat pictures.”

There are two main types of search engines: web-based and enterprise-based.

Web-based search engines are the most common type. They allow users to search for information on the entire internet. Google, Yahoo, and Bing are all web-based search engines.

Enterprise-based search engines are designed for use within a single company or organization. They allow users to search for information that is stored on the company’s internal network, such as employee contact information or customer records.

Examples of enterprise-based search engines include Microsoft SharePoint and IBM Watson Explorer.

Search engines are an essential tool for finding information on the internet. When you use a search engine, you’re using one of the most powerful tools available for finding the information you need.
