Semantic Search

Intermediate

Retrieval based on embedding similarity rather than keyword overlap, capturing paraphrases and related concepts.

Semantic search is like having a smart friend who understands what you really mean, not just the words you use. Instead of looking for exact phrases, it tries to find answers that match the meaning of your question. For example, if you search for 'best places to eat Italian food,' a semantic sear...
