Quick Facts About Search Engines
What is a Search Engine?
A search engine is a vital online intermediary, which is designed to streamline a user’s searches on the World Wide Web.
Search engines are used to reveal information and take the user to his or her desired web addresses.
Search engines yield search results, which are typically presented to the user as a list of results referred to as hits. The hits, whether they are information-based sites, images, or other types of files, all offer the user with an opportunity to observe his or her desired search.
A search engine is typically constructed as a set of programs, which are subsequently aligned and programmed to search for information within a specific realm. The programs then feed or filter into a database where the collated information will be made accessible to individuals conducting a search.
Internet search engines are specially designed to scour the Internet to streamline an individual user’s quest to pull-up or reveal pertinent or desired information. In general, a search engine will help users of the Internet, to organize and display information to make their desired searches readily accessible.
Basic Aspects of a Search Engine:
There are three aspects to a basic engine: indexing, crawling, and searching.
When a search engine ‘crawls’, is looking for new content which was not present during the last crawling session. This process updates files and web pages.
Following the ‘crawl’, the search engine will then index the information. This process pulls out specific keywords and categorizes them based on subject.
Once the information has been indexed, the obtained information is stored in databases. The databases are then scoured when an individual types in a word or phrase to the search engine.
