Types

type Chunk

type Chunk struct {
	Index     int    `json:"index"`
	Text      string `json:"text"`
	ByteStart int    `json:"byte_start"`
	ByteEnd   int    `json:"byte_end"`
}

Chunk represents a single piece of the original text along with its position in the source document.

func ChunkBytes

func ChunkBytes(data []byte, chunkSize, overlap int) []Chunk

ChunkBytes splits data into overlapping chunks of at most chunkSize bytes, preferring to break on paragraph, then sentence, then whitespace boundaries so words are not sliced in half. overlap bytes from the end of one chunk are repeated at the start of the next chunk to preserve context across chunk boundaries (useful for retrieval quality).

type EmbeddedChunk

type EmbeddedChunk struct {
	Chunk

	Embedding []float32 `json:"embedding"`
}
