About this video
You search "happy dog" and keyword search returns zero results. Why? Because no document contains those exact words — even though 1,000 photos of joyful puppies exist. Semantic search converts your query into a vector. "Happy dog" lands right next to "wagging tail" and "playful puppy" in meaning space. But the real move? Hybrid. Run both + RRF fusion in a single query. Meaning lives in the space between words. mixpeek.com/retrievers — semantic, keyword, and hybrid fusion in one API. #SemanticSearch #AI #VectorSearch #MachineLearning #SearchEngineering #NLP
