seek() is the bread-and-butter call. Vector in, ranked hits out.

App → vault → planner → metadata → index → ranked hits.

python

hits = notes.seek(
    query=[0.1, 0.2, 0.3, 0.4],
    top=5,
    threshold=0.3,
)
for h in hits:
    print(h.id, h.distance, h.payload)

From docs/cpp/api-reference/vault.md: SearchResult carries id, distance, data, document, chunk, lineage — all hydrated from the authoritative record store.
