Semantic Search Engine
Project Overview
This is an intelligent search engine that helps users find relevant information quickly and efficiently. Unlike traditional search engines that only look for exact word matches, this system understands the meaning behind your questions and finds relevant content even when the exact words don’t match.
The search engine makes it easy to discover information across hundreds of pages of content, including articles, guides, resources, and more. It’s designed to be fast, accurate, and user-friendly for everyone who needs to find specific information quickly.
