# The Different Types of Search Engines

In today’s era, search engines are indispensable. They assist us in our daily research and continuously feed us with new information. The market leader among search engines is undoubtedly the Internet search engine from the American company “Google.” Google is the most visited website in the world, processing more than 2 trillion searches annually. But what other types of search engines actually exist, and what are they good for? You will find out in this article!

## Internet Search Engines

For information seekers, internet search engines are usually the first point of contact. After a search query, the corresponding software scans the entire internet and lists the relevant results for the user. However, there are different types of internet search engines. Find out what they are here.

The **index-based search engines** analyze the World Wide Web and create their search index according to a specific computer algorithm. Based on this index, relevant results are displayed to the user after a search query. The advantage of such a search engine is undoubtedly the enormous size of the index, which delivers many results in a short amount of time. Examples of these index-based search engines include [Google](http://www.google.de/), Ask, [Bing](https://www.bing.com/?cc=de), or [Yahoo](https://de.yahoo.com/).

The **meta-search engine**, on the other hand, does not rely on its own search index. It is based on the index of the aforementioned index-based search engines. After a search query, a meta-search engine accesses the data from the index-based search engines, weights it, and combines it into a results list. Examples of meta-search engines include [Unbubble](https://www.unbubble.eu/) or [Metager](https://metager.de/). However, meta-search engines are used less frequently today.

Another type of internet search engine is **directories**, where humans have made a preliminary selection of search results. These results are usually organized thematically or alphabetically. Examples of directory-based search engines include online dictionaries, encyclopedias such as [Wikipedia](http://www.wikipedia.de/), or library catalogs. Children’s search engines like [blinde Kuh](https://www.blinde-kuh.de/index) also fall into this category.

## Desktop Search Engines

A desktop search does not scan the internet, but rather a user’s hard drive. Desktop search is immensely helpful when looking for your own files such as emails, PDF documents, or photos. With the help of desktop search engines, files thought to be lost can sometimes be found again in seconds. Especially with desktop search engines that offer real-time indexing, you save a lot of time. Such indexing occurs automatically and takes into account all files on your computer. Furthermore, it is always up to date. An example of such a search engine is the [Lookeen Search](https://lookeen.com/solutions/desktop-search/desktop-search). It can be used seamlessly in Outlook, on the desktop, and even in virtual desktop environments.

## Other Search Engines

A search engine that only searches for content within a specific topic area such as music, sports, etc., is defined as a vertical search engine.

A search engine that only searches a single website, such as the Spotify, Netflix, or YouTube search, is referred to as a domain search.

A search engine that specifically looks for movies, e-books, games, and other files in the Usenet is called a Usenet search engine. However, users of a Usenet search engine must be careful about which files they download, as they may be protected by copyright.

I hope this article has helped you gain a better understanding of the different types of search engines and how they work.
