"Semantic search" optimizes in search engines the understanding of user intent and the contextual meaning of words. Unlike traditional keyword-based search, which relies solely on the presence of specific terms, semantic search considers the relationship between words and their meanings to deliver more relevant search results. This involves analyzing the context, synonyms, and semantic meanings to comprehend what users are genuinely looking for. As a result, it improves search accuracy and enhances the overall user experience by delivering information that aligns closely with user queries.
