Embedding
A numeric representation used to compare relationships between pieces of content.
Group by relatedness
In practice
A question about account recovery can match a passage about resetting a password when both use compatible embeddings.
What to check
Keep the original text, source and access scope. Check model and dimension compatibility before reusing an index.
Common confusion
Similarity is not correctness. Embeddings are not encryption or a substitute for access filtering.
Tell your agent
Add embeddings to the knowledge base. Retain each passage, document version and access scope. Check model and dimension compatibility, and explain any reindexing required before changing models.
