Full-text search is the most common technique used in Web search engines and Web pages. Each page is searched and indexed, and if any matches are found, they are displayed via the indexes. Parts of original text are displayed against the user’s query and then the full text. Full-text search reduces the hassle of searching for a word in huge amounts of metadata, such as the World Wide Web and commercial-scale databases.
