Unit V: Application Domains Search Engine: A search engine is an online answering machine, which is used to search, understand, and organize content's result in its database based on the search query (keywords) inserted by the end-users (internet user). To display search results, all search engines first find the valuable result from their database, sort them to make an ordered list based on the search algorithm, and display in front of end-users. The process of organizing content in the form of a list is commonly known as a Search Engine Results Page (SERP). Google, Yahoo!, Bing, YouTube, and DuckDuckGo are some popular examples of search engines. Large search engines contain millions and sometimes billions of pages; many search engines not only just search the pages but also display the results depending upon their importance. This importance is commonly determined by using various algorithms. For users, a search engine is accessed through a browser on their computer, Smartphone, table, or another device. Advantages of Search Engine: 1) Time-Saving: Search engine helps us to save time by the following two ways -  Eliminate the need to find information manually.  Perform search operations at a very high speed. 2) Variety of information: The search engine offers various variety of resources to obtain relevant and valuable information from the Internet. By using a search engine, we can get information in various fields such as education, entertainment, games, etc. The information which we get from the search engine is in the form of blogs, pdf, ppt, text, images, videos, and audios. 3) Precision: All search engines have the ability to provide more precise results. 4) Free Access: Mostly search engines such as Google, Bing, and Yahoo allow end-users to search their content for free. In search engines, there is no restriction related to a number of searches, so all end users (Students, Job seekers, IT employees, and others) spend a lot of time to search valuable content to fulfill their requirements. 5) Advanced Search: Search engines allow us to use advanced search options to get relevant, valuable, and informative results. Advanced search results make our searches more flexible as well as sophisticated. For example, when you want to search for a specific site, type "site:" without quotes followed by the site's web address. Suppose we want to search for java tutorial on javapoint then type "java site:www.javatpoint.com" to get the advanced result quickly. To search about education institution sites (colleges and universities) for B.Tech in computer science engineering, then use "computer science engineering site:.edu." to get the advanced result. 6) Relevance: Search engines allow us to search for relevant content based on a particular keyword. For example, a site "javapoint" scores a higher search for the term "java tutorial" this is because a search engine sorts its result pages by the relevance of the content; that's why we can see the highest-scoring results at the top of SERP. Disadvantages of Search Engine: There are the following disadvantages of Search Engines -  Sometimes the search engine takes too much time to display relevant, valuable, and informative content.  Search engines, especially Google, frequently update their algorithm, and it is very difficult to find the algorithm in which Google runs.  It makes end-users effortless as they all time use search engines to solve their small queries also.
