#Vector Search is a semantic retrieval approach used directly in these articles.
Definition
Vector search finds similar items by comparing embeddings, making it useful for semantic retrieval where meaning matters more than exact keyword overlap.
Why it matters
It matters when search should understand related meaning, not just string matching, especially in AI retrieval, recommendations, and knowledge interfaces.
In this archive
Here vector search appears in semantic search, RAG infrastructure, ranking quality, embedding pipelines, and architecture choices around AI retrieval systems. It currently appears across 2 categories, mainly AI, Updates.
