85% of web users use search engines to find information. However, the search engines are currently lacking in comprehensive and timeliness, and do not index sites equally.
The Deep Web
At least 3.74 billion web pages were indexed as of July 2023 according to WorldWideWebSize.com. Even worse is the number of database-driven web sites is increasing exponentially, and each site is creating pages dynamically—pages that are hard for traditional search engines to reach. Such search engines crawl and index static HTML pages; they do not send queries to web databases. The information hidden inside web databases is called the “deep Web” in contrast to the “surface Web” that traditional search engines access easily.
