At query time, embedding_search embeds the incoming query using the same model — this is important, the query and the chunks must live in the same vector space — then computes cosine similarity between the query vector and every stored chunk vector. Cosine similarity measures the angle between two vectors: a score of 1 means identical direction, 0 means completely unrelated, and negative values mean opposite meaning.
