Nowadays, few people can imagine their life without search engines. They’ve become a necessity in our daily life. The search engine Google has become so ubiquitous, we don’t talk about looking something up anymore, we just Google it! And how much easier does it make basically everything? Whenever you want to know anything, just take your phone or computer and look it up.
The programs, also called “crawlers”, ‘spiders’, ‘bots’, or ‘robots’ will create the search engine’s database and show results according to the keywords users are searching for. In the course of this, web page changes will be caught, which affects how web pages are listed in the search results.
They are arguably the most effective search engines if you are looking for a rather specific search topic, and are the most likely to show you relevant information. On the contrary, you will probably find them less efficient if you are looking for more general topics, as they may show many irrelevant responses as well.
Popular choices of crawler-based search engines are:
⇒ Google, Bing, Yandex, Yahoo!, Baidu
Hybrid search machines
Finally, there are the hybrid search machines that use bot crawler-based as well as manual indexing for listing their search results. Most of the popular search engines like Google uses crawlers as the primary mechanism while there still is some manual filtering to remove spammy and copied sites.
Human-powered directories are disappearing, and hybrid types are becoming more and more dependent on their crawler-based search engines, rather than human power.
Popular choices of hybrid search engines are:
⇒ Yahoo, Google
Desktop search engines
A desktop search does not search the Internet, but rather a user’s hard drive. The desktop search is extremely helpful when researching your own files such as e-mails, PDF documents, or photos. With the help of desktop search engines, files believed to be lost can be found again in a matter of seconds. You save a lot of time, especially with desktop search engines that offer real-time indexing. Such indexing is done automatically and takes all files on your computer into account. In addition, it is always up to date. An example of such a search engine is Lookeen search. It can easily be used in Outlook, on the desktop, and even in virtual desktop environments.
