Dive into a live code review session where experts build a semantic search engine using Typescript. Explore fundamental concepts of semantic search, compare it with lexical search, and delve deep into the codebase of Pinecone's semantic search Typescript example. Learn about embeddings, CSV loaders, Transformers.js, and the indexing process. Discover techniques for batch embedding and parallelizing embeddings using workers. Follow along as the speakers demonstrate querying the index and provide insights on implementing semantic search effectively.
