Search Engine

Save

Search engines are software systems that index and search through large collections of data to help users find the information they're looking for. They use a variety of techniques to do this, including crawling the web to collect data, indexing the data to make it searchable, and ranking the results to show the most relevant information first.

How Search Engines Work

Search engines work by crawling the web, which is the process of following links from one web page to another. As they crawl, they collect data about each page, such as the page's title, content, and links. This data is then stored in an index, which is a large database of all the pages that have been crawled. When a user searches for something, the search engine looks up the relevant pages in the index and ranks them based on how relevant they are to the user's query.

Different Types of Search Engines

There are many different types of search engines, each with its own strengths and weaknesses. Some of the most popular search engines include:
