AI-Powered Search Implementation

The Challenge

An e-learning platform with thousands of courses was struggling with search relevance. Users frequently couldn't find relevant content even when it existed, leading to high bounce rates and support tickets. Their keyword-based search failed to understand user intent and couldn't surface conceptually related content. They needed a solution that could understand natural language queries and provide contextually relevant results.

Our Approach

We analyzed search logs and user feedback to understand common query patterns and pain points. We designed a hybrid search architecture combining traditional keyword search with semantic vector search for the best of both worlds. The hybrid approach handles both natural language queries and exact-match lookups effectively. We also implemented a RAG (Retrieval-Augmented Generation) layer to generate AI-powered course recommendations and summaries based on retrieved results.

The Solution

Built on Python with FastAPI, the search system uses OpenAI embeddings to convert course content and queries into semantic vectors stored in Pinecone. The hybrid search combines BM25 keyword scoring with cosine similarity for comprehensive results. A React-based search interface provides instant suggestions, faceted filtering, and AI-generated course recommendations. The system captures user interaction data such as click-through rates and search refinements to inform future relevance improvements.
