Embedding Vector Search into Legacy Apps

A practical guide to upgrading your infrastructure with AI capabilities.

Vector search shouldn't require ripping out your entire backend. We've successfully integrated pgvector alongside existing PostgreSQL databases, allowing legacy applications to perform semantic search without touching the core transactional schema. By running hybrid lexical and semantic search (fusing BM25 with vector embeddings), we deliver state-of-the-art AI retrieval directly into older enterprise architectures.
