Full-Text Search is a technique used in databases and search engines to find specific words or phrases within large volumes of text. Unlike simple keyword searches, it analyzes the entire content of documents, allowing for more complex queries. This method can identify relevant results based on context, synonyms, and variations of words, making it more effective for retrieving information. This search capability is commonly used in applications like Google, Microsoft Word, and various database management systems. Full-Text Search enhances user experience by providing faster and more accurate results, especially when dealing with extensive text data, such as articles, books, or web pages.
