What is "when a search is run?

When a search is run, the search engine algorithm quickly scans its vast database of websites and returns the most relevant pages based on the user's search query. The results are ranked based on a variety of factors such as the user's search history, the authority of the website, the quality of the content, and the relevance of keywords. The search engine utilizes a series of complex algorithms and filters to provide the user with the most accurate and useful information possible. Additionally, search engines rely heavily on natural language processing and machine learning to better understand user intent and deliver more personalized results. Ultimately, the objective of a search engine is to provide the most relevant and useful information to the user in the shortest amount of time possible.
