Unlike simple keyword matching, it indexes and searches through all words, understanding their context, frequency, and relationships. This allows users to quickly locate documents containing specific phrases, words, or concepts within large volumes of text, making it highly effective for content-heavy websites, digital libraries, and enterprise databases.
