Developer Builds AI Knowledge Base with Aurora pgvector and Next.js

By Meridian48 News Desk · Summarised from DEV Community ·

The app stores 3072-dimensional vector embeddings and uses cosine similarity to find relevant results. It combines pgvector, ltree, and tsvector extensions for hybrid search across structured and chat data.
