Constants ¶
const ( OllamaDefaultURL = "http://localhost:11434" OllamaDefaultModel = "nomic-embed-text" VoyageDefaultModel = "voyage-3" )
Defaults used by each backend when embedding.model or embedding.base_url is not set. core.ResolveBackends applies them.

Types ¶
type Adapter ¶
type Adapter interface {
// Embed converts text to a normalised float32 vector.
Embed(ctx context.Context, text string) ([]float32, error)
}
Adapter defines the contract for all embedding backends. Implementations: voyage.go, ollama.go.
Implementations MUST return L2-normalised vectors (‖v‖₂ = 1). The search layer assumes this when interpreting distance scores — an L2 distance threshold of 1.0 corresponds to cos_sim ≈ 0.5 only for unit vectors. Both Voyage AI and Ollama nomic-embed-text return normalised vectors by default; any new adapter that does not must normalise before returning.
All embeddings in the DB must use the same model and dimensions.
type OllamaAdapter ¶
type OllamaAdapter struct {
// contains filtered or unexported fields
}
OllamaAdapter implements EmbeddingAdapter using a local Ollama server.
func NewOllamaEmbeddingAdapter ¶
func NewOllamaEmbeddingAdapter(baseURL, modelName string) *OllamaAdapter
NewOllamaEmbeddingAdapter creates an adapter pointed at the given Ollama base URL.
type VoyageAdapter ¶
type VoyageAdapter struct {
// contains filtered or unexported fields
}
VoyageAdapter implements EmbeddingAdapter using the Voyage AI REST API.
func NewVoyageAdapter ¶
func NewVoyageAdapter(apiKey, model string) *VoyageAdapter
NewVoyageAdapter creates a new Voyage AI embedding adapter.
