What is vector search? In this breakdown, learn how vector search leverages machine learning to capture the meaning and context of unstructured data by transforming it into a numeric representation that is stored in a vector database. This video also explains the difference between sparse and dense embeddings, and how vector search differs from semantic search and lexical search.

David Tippet, Search Engineer at GitHub, shares how Elastic powers GitHub’s massive search platform and enables a seamless developer experience. He explains how GitHub balances AI-driven semantic search with traditional keyword search, ensuring accuracy for millions of diverse users, from engineers to security researchers.

In this session, we’ll show you how *hybrid search using Elastic* lets you assign weights to different search types — for example, giving semantic search three times more influence than lexical search. This lets you fine-tune the balance between precise keyword matching and broader, context-aware results.

Ever wondered how Wikipedia loads answers instantly? Or how does your Uber update in real-time? That’s Elastic Search working behind the scenes. In this video, I break down how Elastic powers lightning-fast, scalable search for complex data from ride requests to stock prices.

In this session, we’ll show you how Elastic's ELSER takes a single token like _“Terminator”_ and expands it into semantically related terms such as _software, alien, computer technology,_ and _Connor_ (for John Connor). This makes search results more relevant, even when the exact keyword isn’t used.

What is semantic intent, and why is it crucial in the age of *AI search?* In this episode of Quick Question, we break down how semantic *intent interprets* the meaning behind your query in semantic search. About Elastic Elastic, the Search AI Company, enables everyone to find the answers they need in real time, using all their data, at scale. Elastic’s solutions for search, observability, and security are built on the Elastic Search AI Platform — the development platform used by thousands of companies, including more than 50% of the Fortune 500.
