A search engine is a type of software that helps people find information on the internet. It does this by searching through all the websites that are available on the internet and finding the ones that contain the information that the person is looking for.

There are many different types of search engines, but they all work in basically the same way.

When you type in a search query, the search engine looks through all the websites that it knows about and tries to find the ones that are most relevant to your query. It then ranks the results based on how relevant they are, and displays them to you in order of relevance.

1 - Search engine types:

Search engines are classified based on the type of data they collect:

• Web page search engine: when you perform a search, it returns the most relevant web page as a result.
• Image Finder: Crawls images and displays a mosaic of relevant results.
• Video Finder: Analyzes videos and displays those that are interpreted to be relevant to the search.
• File Finder: Returns results based on the file's name or type.

2 - How search engines function:

Regardless of the type of search engine, its operation is consistent.

• Registration in the database: All available data is tracked by bots.
• Categorization of Data: All crawled data is classified using categorization algorithms.
• Query in the database: A query is received, and all stored information is searched.
• Sample of results: Hierarchical results are provided, with the most relevant appearing first.

Search engines are constantly changing and improving their algorithms, in order to provide better results for their users.
