What Happens to a Vector Index When Documents Change?

Effective vector-index management requires a defined lifecycle for document revisions, deletions, and embedding-model changes, beginning with stable identities for documents, revisions, chunks, and source locations. Source documents should be distinguished from their derived chunks, with metadata showing which version is active and policies governing whether revisions replace all chunks or only selected records. Version transitions should be prepared and activated atomically where possible, using source versioning or another monotonic boundary to prevent delayed older updates from overwriting newer data. Deletion must address index entries, source retrieval paths, caches, synchronization jobs, and retry queues rather than relying only on empty search results. Embedding-model migrations should be treated as index migrations, retaining model-version metadata, evaluating results against fixed questions, supporting parallel indexes and rollback, and preserving source IDs to explain ranking differences. Managed ingestion workflows should be tested with individual document revisions for readiness and retrieval before applying changes across an entire corpus.
