// Indexer stores documents (and optionally their vector embeddings) in a

// Store accepts a batch of [schema.Document] values and returns the IDs
// assigned to them by the backend. When [Options.Embedding] is provided,
// the implementation generates vectors before storing — the same embedder
// must be used by the paired [retriever.Retriever].
//
// Use [Options.Index] to choose a backend index at call time, and
// [Options.SubIndexes] to write documents into logical sub-partitions within
// the same store.
