What is the search engine? Search engine (search engine) is software accessed on the Internet to search the database of information according to the user’s query. This tool provides a list of results that best match what users are trying to find.
Currently, there are many different search engines available on the Internet, each with their own unique features. The first search engine developed was Archie , used to search FTP files and the first text-based search engine was Veronica.
Currently, the most popular and famous search engine is Google. Other popular search engines include AOL, Ask.com, Yahoo, Bing, DuckDuckGo and Yahoo.
How to access the search engine
For users, the search appliance is accessed through a browser on a computer, smartphone, tablet or other device.
Today, most new browsers use the address box, which is the text box at the top of the browser. The address bar allows users to enter URLs or search queries. You can also visit one of the main search engine homepage to perform a search.
How does search engine work?
Because large search engines contain millions and sometimes billions of pages, many search engines display results depending on how important they are. This importance is usually determined using different algorithms.
As illustrated above, the source for all search engine data is collected using a crawler (visiting each page on the Internet and gathering its information – this process is called crawl ).
When a page is crawled, the data in the page is processed and indexed. Typically, this may involve the steps below.
Ignore stop words (words ignored by search engines partially or completely).
Record the remaining words on the page and how often they are used.
Record links to other pages.
Write information about any images, audio and media content embedded on the page.
The collected data is used to rank each page (ranking). These rankings then determine which pages to display in search results and in what order.
Finally, once the data is processed, it is divided into files, inserted into the database or loaded into memory, where it is accessed when the user performs a search.
Do all search engines give the same results?
Not necessarily that. Search engines use proprietary algorithms to index and correlate data, so every search engine has its own approach to finding what the user is trying to find.
Results can be based on your location, what you searched for, and what results other users searched for the same query. Each search engine takes these factors into consideration and gives you different results.
Where is the best search engine?
No search engine is better than another. Many people can argue that Google’s search engine is the best, as it’s most popular and famous.
